A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/s from the edge of a 45.0 m high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored.
1.At what angle above the horizontal should the ball be thrown so that the runner will catch it just before it hits the ground?
2.How far does the woman run before she catches the ball?

A ball is thrown upward from the ground with an initial speed of 20.0 m/s; at the same instant, another ball is dropped from a building 12 m high. After how long will the balls be at the same height?
A man is standing on a ledge when he throws a ball. The speed of the ball when released from his hand is 20.0 m/s . The ball is 45.0 m above the ground when released from the man's hand. On the ground below, a boy begins running away from a point directly below the man on the ledge at a constant speed of 6.00 m/s. The boy runs in a straight line along the ground. As the boy runs,...
A soccer ball is kicked from the ground with an initial speed of 19.5 m/s at an upward angle of 45°. A player 55 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground?
A stone is thrown vertically upward with a speed of 12.0 m/s from the edge of a cliff 75.0 m high; (a) How much time does it take in order for the stone to reach the maximum height? (b) What is the maximum height measured from the edge of the cliff? (c) How much time (from the instant the stone is projected) does it take to reach the bottom of the cliff? (d) What is its speed just before reaching...
A ball is thrown upward from the ground with an initial speed of 16.6 m/s; at the same instant, another ball is dropped from a building 20 m high. After how long will the balls be at the same height above the ground?
A ball is thrown upward from the ground with an initial speed of 20.2 m/s; at the same instant, another ball is dropped from a building 20 m high. After how long will the balls be at the same height?
A soccer ball is kicked from the ground with an initial speed of 17.6m/s at an upward angle of 42.5 degrees. A player 49.4 m away in the direction of the kicks starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.
A toy is thrown vertically upward with a speed of 12m/s from the edge of a cliff 75m high. How much later does it reach the bottom of the cliff? Whats its speed just before hitting the ground? What total distance did it travel?
A stone is thrown vertically upward with a speed of 13.5 m/s from the edge of a cliff 75.0 m high. A.) how much later doesnit reach the bottom of the cliff? In seconds B.) what is it’s speed just before hitting? In m/s C.) what total distance did it travel? In m
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the speed of the...
