- You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground. How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway? Express your answer using one significant figure.You're helping a friend move in to their apartment on the second floor, and decide it makes more sense to throw a box straight up from the ground to the open window in the apartment, 5.00 m above the ground. Your friend leans out the window and catches the box while it's moving upward at 2.40 m/s. What is the speed of the box as it left your hand?An elevator starts from the ground floor and moves up with a constant speed of 4 m/s. If a bolt falls off the elevator 2 seconds after it start moving,A) How long does it take for the bolt to hit the ground?B) What is the speed of the bolt just before it hits the ground?C) If the elevator keeps moving after the bolt falls off, what is the distance between the elevator and the bolt when the bolt is 1 meter from the ground?
- Standing from the top of the building and I want to hit the root of the big tree below. The height of the building is 90m and the tree is 60m away from the foot of the building. If a throw a stone with a speed of 18 m/s, will I hit the target? If yes explain it. If no at what distance will I miss the target?Answer parts a, and b of the following question. 7. a) Arthur and Betty start walking toward each other when they are 100 m apart. Arthur has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. How long does it take for them to meet? b) The captain orders his starship to accelerate from rest at a rate of "1 g" (1 g = 9.8 m/s2). How many days does it take the starship to reach 10% the speed of light? (Light travels at 3.0 × 108 m/s.)A prankster flips a coin off of the Empire Building at a height of 1054 feet above the ground. The initial vertical velocity of the coin is 1.20m/s. In real life, air resistance would limit the maximum speed the coin can attain during its fall, but if air resistance were not a factor and assuming it has practically no horizontal motion, answer the following questions. (1 foot = 0.3048m) a. What would the coin's velocity be when it hits the ground? b. How long would it take to hit? c. How high would the coin be halfway through the total falling time, and how fast would it be falling then?
- OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 8.14 m/s^2. When you drop a ball from a height of 2.15 m, it hits the floor 0.200 s later. What is the value of g for the alien world below you?A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 18.0 m/s. The cliff is 50.0 m above a flat, horizontal beach. How long after being released does the stone strike the beach below the cliff? With what x and y speed will the stone impact the ground?QUESTION 10 A ball is thrown horizontally from the top of a building 0.10 km high. The ball strikes the ground at a point 65 m horizontally away from and below the point of release. What is the speed of the ball just before it strikes the ground? O 47 m/s O 39 m/s O 43 m/s O 14 m/s O 36 m/s
- Sometime in the future, we will develop a space ship which can go up to half the speed of light. On a flight to the nearest star which is 4.2 light years away, we will keep the acceleration up to one g. How long will the trip take? (The trip will have three sections, the first accelerating up to maximum speed, the second at constant speed, and the third decelerating at - g to rest at the destination.)Two cars are initially (2.50+C) km apart on a straight road. If the cars are moving toward each other, car 1 with a speed of (5.40+A) m/s and car 2 with a speed of (7.20+B) m/s, how many seconds will it take before the cars meet? Round your answer to three significant figures. A=8 B=7 C=20You are at the top of the Empire State Building on the 102nd floor, which is located 373 m above the ground, when your favorite superhero flies over the building parallel to the ground at 60.0 % the speed of light.
