1. Ball A was released from the cliff of height H; ball B was released from the cliff of height 2H. The ratio of velocity of ball B to ball A just before they hit the ground is: A) 2 B) 2 1/2 C) 1 D) sqrt(2) E) 1/sqrt(2) 2. Object is thrown up with some initial velocity. No air resistance is present. We can conclude that: a) Acceleration on the way up is greater than acceleration on the way...

2) A ball is dropped from rest at the top of a high cliff. It takes 10.00 seconds for the ball to reach the ground below. Find: a) the height of the cliff, b) the velocity of the ball hitting the ground below, c) the time it takes for the ball to fall half of the cliff's height, and d) the velocity at this halfway point. (Remember acceleration due to gravity is -9.800 m/s^2).

A rock is thrown from the top of a cliff with height h and the sound of the rock hitting the ground is heard 20 seconds from when the rock is thrown. What is the height of the cliff? (temperature=0 degrees Celsius) Use Total Time=20 seconds= time for the rock to hit the ground + time for sound of rock to reach the person at the top of the cliff.

A stone is thrown from the top of a cliff with the initial velocity of 20.0 m/s straight upward. The cliff is 50.0 m high and the stone just misses the edge of the cliff on its way down. Determine (a) the time needed for the stone to reach its maximum height; (b) the maximum height, as measured from the ground; (c) the time needed for the stone to return to the level of the thrower; (d) the velocity of...

Two Buildings A and B are each of height H as measured from the ground and are located a distance L apart as shown in the figure. A ball is shot horizontally with a velocity v0 ​from building A such that it just hits the middle of building B before hitting the ground. At what new velocity v' would the ball have to be shot from building A such that the ball now hits Building B one-quarter of the way...

A ball, mass is 8 kg, is thrown from the top of a 30 m cliff with a velocity of 20 m/s straight up. The ball misses the cliff on the way down. Ignore air resistance. Use work and conservation of energy to find the following values. a. what is the work done by gravity while the ball is in the air? b. what is the maximum height of the ball? c. what is the magnitude of the velocity just...

A 1-kg ball is released from a height of 6 m, and a 2-kg ball is released from a height of 3 m. Air resistance is negligible as they fall. Which of the following statements about these balls are correct? (There could be more than one correct choice.) Both balls will reach the ground with the same speed. As they reach the ground, the 1-kg ball will have more kinetic energy than the 2-kg ball because it was dropped from...
