•• I P A white-crowned sparrow flying horizontally with a speed of 1.80 m/s folds its wings and begins to drop in free fall. How far does the sparrow fall after traveling a horizontal distance of 0.500 m? If the sparrow’s initial speed is increased, does the distance of fall increase, decrease, or stay the same? Graph and solve .
You buy a plastic dart gun, and being a clever physics
student you decide to do a quick calculation to find its
maximum horizontal range. You shoot the gun straight
up, and it takes 5.6 s for the dart to land back at the
barrel.
• Part A
What is the maximum horizontal range of your gun?

Problem 5
You testify as an expert witness in a case involving an accident in which car A slid into the
rear of car B, which was stopped at a red light along a road headed down a hill. You determine
that the slope of the hill is 0 = 12.0°, that the cars were separated by distance d = 24.0 m
when the driver of car A put the car into a slide, and that the speed of car A at the onset of
braking was vo
18.0 . With what speed did car A hit car B if the coefficient of kinetic
friction was 0.60?

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.

- You can use any coordinate system you like to solve a projectile motion problem. To demonstrate the truth of this statement, consider a ball thrown off the top of a building with a velocity v at an angle with respect to the horizontal. Let the building be 50.0 m tall, the initial horizontal velocity be 9.00 m/s, and the initial vertical velocity be 12.0 m/s. Choose your coordinates such that the positive y-axis is upward, the x-axis is to the right, and the origin is at the point where the ball is released, (a) With these choices, find the balls maximum height above the ground and the time it takes to reach the maximum height. (b) Repeat your calculations choosing the origin at the base of the building.arrow_forwardIn 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77 m. What was the initial speed of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus, 38° will give a longer range than 45° in the shot put.)arrow_forwardYou can use any coordinate system you like to solve a projectile motion problem.
