Two students are on a balcony 18.6 m above the street. One student throws a ball (ball 1) vertically downward at 13.1 m/s; at the same instant, the other student throws a ball (ball 2) vertically upward at the same speed. The second ball just misses the balcony on the way down. (a) What is the difference in the two ball's time in the air? (b) What is the velocity of each ball as it strikes the ground?
A ball of mass 0.3 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 17 m/s at angle of 47 ◦ above the horizontal. The top of the fence is 6 m high. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s2 (meters/seconds/squared). 1) How far above the top of fence will the ball pass? Consider the diameter of the ball to be negligible. Answer in units of m. 2) What is the vertical component of the velocity when the ball reaches the plane of the fence? Answer in units of m/s.

A person stands on a diving board and tosses a stone into a swimming pool. The stone is thrown from a height of 2.9 m above the water surface with a velocity of 2.8 m/s at an angle of 38° above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the stone enters the water, it moves in a straight line in the direction of the velocity it had when. it struck the water. If the pool is 4 m deep, how much time elapses between when the stone is thrown and when it strikes the bottom of the pool? ttotal = S
Irina, standing on the edge of a cliff, throws a stone at a 40-degree angle above the horizontal with an initial speed of 10.0 m/s. The instant before the stone hits the ground below, it is traveling at a speed of 63 m/s. If Irina were to throw the other rock at a 40-degree angle below the horizontal from the cliff instead, with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground? Ignore any effects of air resistance

When a chronometer begins with a time of zero seconds, matching soccer balls have a horizontal separation, d=6.28m. The ball on the left is released from the ground with an initial velocity of magnitude v0 directed toward the other soccer ball. The ball on the right has an initial height h1=3.17m and is momentarily at rest. A short time later, the matching soccer balls collide at the collision point, C, at a height h2-1.69m above the ground, as indicated on the diagram. Ignore the finite size of the balls, and additionally ignore any air resistance. (Dimensions are not to scale.) Part (a) Given the numeric values in the problem statement, tabulate the elapsed time, in seconds, at which the matching soccer balls collide. Part (b) Given the numeric values in the problem statement, tabulate the magnitude, in meters per second, of the initial velocity of the soccer ball on the left.
