A clown juggle balls while doing other activities. In one act, she throws a ball vertically upward, and while it is in the air, she runs to and from a table 5.5 m away at constant speed of 3.5 m/s, returning just in time to catch the falling ball. With what minimum initial speed must she throw the ball upward to accomplish the act?

Dock diving is great form of athletic competition for dogs of all shapes and sizes. Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.02 m/s at an angle of 25.0° with respect to the surface of the water. Sheba begins at a height of 0.840 m above the surface of the water. What is her total time of flight up until the instant before she hits the water? Express your answer in seconds.

A snowball rolls off a barn roof that slopes downward at an angle of 40°. The edge of the roof is 14.0 m above the ground, and the snowball has a speed of 7.00 m/s as it rolls off the roof. Ignore air resistance, how far from the edge of the barn does the snowball strike the ground if it doesn't strike anything else while falling? If a man 1.9 m tall is standing 4.0m from the edge of the barn, will he be hit by the snowball?

A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0degrees above the horizontal. The rocket is fired towards an 28.8m high wall, which is located 25.0m away. The rocket attains its launch speed in a neglibly short period of time, after which its engines shut down and the rocket coasts. By how much time does the rocket clear the top of the wall?

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.63 m/s at an angle of 79.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?      m/s

A) The best leaper in the animal kingdom is the puma, which can jump to a height of 3.7 m when leaving the ground at an angle of 45°. With what speed must the animal leave the ground to reach that height? m/s = B) A brick is thrown upward from the top of a building at an angle of 20° to the horizontal and with an initial speed of 11 m/s. If the brick is in flight for 2.6 s, how tall is the building? m =

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

two cars start 220 m apart and drive toward each other at a steady 10.0 m/ s. On the front of one of them, an energetic grasshopper jumps back and forth between the cars with a constant horizontal velocity of 15.0 m/s relative to the ground. The insect jumps in the instant he lands, so he spends no time resting on either car. what total distance does the grasshopper travel before the car hits?

In 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, in m/s, 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.) v0 =
