An entertainer juggles balls while doing other activities. In one act,she throws a ball vertically upward, and while it is in the air, sheruns to and from a table 5.50 m away at constant speed of 2.50 m/s,returning just in time to catch the falling ball. (a) with whatminimum initial speed must she throw the ball upward toaccomplish the act? (b) how high above its initial position is the balljust as she reaches the table?

Given information: The distance of the table from the point of projection (d) = 5.50 m The speed of…

A puma (aka cougar or mountain lion) is one of the best jumpers among all animals. It can jump to a height of 12.0 feet high when it leaves the ground at an initial angle of 45°. What is the initial speed (in m/s) of the puma as it leaves the ground?
A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0 degrees 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 does the rocket clear the top of the wall (in meters)?
A player throws a ball [You can assume g ≃10 m/s2; Ignore air resistance. 1ft=0.305m] a) At what initial speed must the robot throw the ball to make the shot, given the sketch above?

From the edge of a high cliff overlooking a flat valley, you shoot a cannonball horizontally over the valley with an initial speed of 120 m/s. If the cliff is 400 m above the valley floor, how far does the cannonball travel in the horizontal direction before landing on the ground?
A rescue plane flying horizontally at 252 km/hr in still air spots a survivor in the ocean 180 m directly belowwhen it releases an emergency kit. Air resistance slows the descent such that the kit falls with a constant verticalacceleration of 6.00 m/s2 downward. Due to the shape of the kit, air resistance in the horizontal direction isnegligible. How far from the survivor does the kit land in the water?
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?
Your little sister is running to the park in your neighborhood at a speed of 3.90 m/s when you suddenly realize she left her favorite playground ball behind. You throw her ball horizontally out the window of your apartment which is at a height of 45.0 m above the street and directly above the sidewalk. You throw the ball 8.00 seconds after she has passed below your window and she catches the ball! a) Ignoring air resistance, what is the initial speed that you must throw her ball so she can catch it just before it reaches the ground? b) How far down the sidewalk from the window is your sister when she catches her ball?

A ball is thrown at a 40-degree angle above the horizontal across level ground. It is released from a height of 2.00 m above the ground with a speed of 18.0 m/s. What is the maximum height above the ground that the ball reaches?
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
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 =
