Solve the following motion problems. 1. A ball is thrown vertically from a point 30 feet above the ground. (a). At what velocity must it be thrown for it to strike the ground in 2 seconds? Is the ball initially thrown vertically upward or downward? (b). What is its velocity when it strikes the ground? (c). Where is the ball one second after it was thrown initially? Is it moving upward or already on its way down? (Hint: Take the time and displacemnet at the maximum point of its flight by setting v=0.)

A frog leaps off the ground at an angle of 20 degrees to the horizontal. It's in the air for .84 seconds before landing at the same height from which it took off. a) Given this leap, what is the initial velocity of the frog? b) How far does the frog jump?
In a Ballistic Pendulum Experiment, a ball is shot horizontally from a launcher which is located 0.55 meters above the floor. The ball lands 2.52 meters from the front edge of the launcher. 1. How long was the ball in the air until it hit the ground? 2. What is the muzzle velocity of the ball as it exits the launcher?
Please use the formulas in the picture. Show your solution in a paper. Thank you! QUESTION: An object is thrown downward with an initial (t=0) velocity of 10 m/s from the height of 60 m above the ground. At the same instant (t=0), a second object is thrown upward from ground level with speed of 40 m/s. At what height above the ground will the two balls pass each other?

How do you solve this question using the velocity or acceleration method?
You throw a ball up at some angle above the horizontal so that its velocity is (v0x, v0y). You then run 22.0 m forward on level ground and catch the ball 2.90 s later at the same altitude it was released from. a) How high above the release point did the ball reach? b) What was the horizontal component of the ball’s initial velocity, v0x? c) What was the vertical component of the ball’s initial velocity, v0y?

Find, a.) the height of tabletop above the floor. b.) the horizontal distance from the edge of the table to the point where the book strikes the floor. c.) the horizontal and vertical components of the book's velocity, and the magnitude and direction of its velocity, just before the book reaches the floor.
The 2010 Soccer World Cup played here in South Africa will always be a history to remember. That when Simphiwe Tshabalala scored a beautiful long range shot when Bafana Bafana was playing against Mexico in the opening game. After kicking the ball, it touched the goal-line (at ground level) 35.00 m. Use the above information to answer questions 12 to 15. Calculate: 12. Calculate the time at which the ball reached this maximum height. 13. The angle at which Tshabalala kicked the ball relative to the ground. 14. The vertical component of the initial velocity, Voy 15. The initial velocity at which he kicked the ball.

A bowling ball travelling with a constant velocity hits the pins at the end of a bowling lane 68m long. The bowler hears the ball hitting the pins 4.36s after the ball is released from his hands. What is the velocity of the ball? (speed of sound is 343 m/s) Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball 48m/s up into the air, how fast will it be moving at a height of 26.72cm? How much time has elapsed upon reaching this height? A skydiver jumped out of a plane to shoot a skydiving scene for a certain spy movie. At what point in time should this spy-wannabe open his parachute when he is aware that the plane was at the altitude of 61m, and he needs to open it at a height of 366.49m?
