dynamics (mech) A game requires that two children throw a ball upward as high as possible at the same point and then to run horizontally in opposite directions. The child who travels the greater distance before their thrown ball impacts the ground winds. One child throws the ball at his arm’s height of 4.5 ft at a speed of 69 ft/sec and runs leftward at a speed of 16 ft/sec. The other child does the same but was able to throw better releasing his ball at a heigh of 6 ft at a speed of 71 ft/sec then runs rightward at a speed of 17 ft/sec. Which child wins the game?

(a) A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 32° ramp at a speed of 40.0 m/s (144 km/h). How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 20.0 m long? (b) Discuss what your answer implies about the margin of error in this act—that is, consider how much greater the range is than the horizontal distance he must travel to miss the end of the last bus. (Neglect air resistance.)

A stone is thrown upward from the top of a building at an angle of 70° to the horizontal and with an initial speed of 24m/s. The height of the building is 32m. a) How high above the initial point is the stone at it highest? b) How long does it take for the stone to hit the ground? c) where does the stone hit the ground? d) calculate the velocity and the direction of the stone at the moment of impact with the ground.
A student stands at the Edge of a Cliff and throws a Stone horizontally Over the edge with a speed of 18 m/s. The cliff is 50.0 m above a flat, horizontal beach. A) What are the components of the initial velocity? B) How long after being released dos the stone strikes the beach below the cliff? C)With what speed does the stone land? Your final answers should be written using scientific notation
A student throws a 2.5kg ball horizontally off the top of a building with an initial speed of 4.25 m/s. At the same time, another student throws a 1.12kg ball along the same trajectory with the same initial speed. Which of the balls hits the ground first? a. The 2.5kg ball. b. They hit at the same time. c. The 1.12kgball.
Chapter 04, Concept Question 04 You are to launch a rocket, from just above the ground, with one of the following initial velocity vectors: (1) w = 201 + 70j, (2) w = -20i + 70j. (3) w = 20i – 70j . (4) w = -20i – 70j. In your coordinate system, x runs along level ground and y increases upward. In the following questions, you will need to rank these vectors. If multiple vectors rank equally, use the same rank for esch, then exclude the intermediste ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all vectors rank equally, rank esch as '1" LINK TO TEXT Rank the vectors according to the launch speed of the projectile, greatest first. Vector 1.. V Vector 2 Vector 3 |-- v Vector 4 -- v 1. Greatest launch speed 2. Second greatest launch speed 3. Third greatest launch speed 4. Fourth greatest launch speed Rank the vectors according to the time of flight of the projectile, greatest first. Vector 1.- v Vector 2…
student throws a heavy red ball horizontally from a balcony of a tall building with aninitial speed v0. At the same time, a second student throws a lighter blue ball horizontally fromthe same balcony with an initial speed v0 /2. Ignoring air resistance, which of the followingstatements must be true?a. The red ball hits the ground with the greater speed.b. Both balls hit the ground with the same vertical velocity component.c. Both balls hit the ground with the same angle of impactd. The balls reach the ground at the same instant. More than one of the statements can be true.
As you walk briskly down the street, you tossa small ball into the air. (a) If you want the ball to land in your handwhen it comes back down, should you toss the ball straight upward,in a forward direction, or in a backward direction, relative to yourbody? (b) Choose the best explanation from among the following:I. If the ball is thrown straight up you will leave it behind.II. You have to throw the ball in the direction you are walking.III. The ball moves in the forward direction with your walkingspeed at all times.
3. A game requires that two children throw a ball upward as high as possible at the same point and then to run horizontally in opposite directions. The child who travels the greater distance before their thrown ball impacts the ground wins. One child throws the ball at his arm’s height of 4 feet at a speed of 70 ft/sec and runs leftward at a speed of 16 ft/sec. The other child does the same but was able to throw better releasing his ball at a height of 6 feet at a speed of 64 feet second then runs rightward immediately at a speed of 17.8 ft/sec. Which child wins the game?
a guy is throwing pumpkins off a five story (15 meters high) building and wants the messiest result possible (highest velocity impact). a) he first throws a pumpkin downward at 45 degrees below the horizon at 15 m/s. how fast does the pumpkin hit the ground? at what angle does it hit? b) he then throws a second pumpkin upward with the same velocity 45 degrees above the horizon. how fast does the second pumpkin hit the ground? c) which strategy (throwing the pumpkin up or down) results in a higher velocity impact? think about why this might be
IM-5 Jae throws a 0.350kg ball so that it is traveling at 7.50m/s y toward a wall, approaching the wall at an angle of 35.0° as shown in the figure to the right. After hitting the wall, the speed of the ball is still 7.50m/s but its direction has changed and it is now traveling at an angle of 35.0° away from the wall as shown to the right. a) Sketch on your paper a figure like the one shown to the right and show the vectors for the momentum before impact, PB, the momentum after impact, PA, and use them to find Ap, the change in momentum for the ball. Clearly label each vector. b) Calculate the sign and magnitude of Apx. the change in momentum in the x direction. c) Calculate the sign and magnitude of Apy the change in momentum in the y direction. d) If the collision lasts for 0.150 seconds, find the magnitude of the average force on the ball during the collision. What is the direction of the average force on the ball during the collision? Answer this by showing an arrow and label it as…
