A ball is dropped from the top of a cliff. the height of the cliff is 1000m. a) how long does for the ball to hit the ground if the cliff is on earth (g= 9.80 m/s^2)? b) how long does it take if its on the moon (g= 1.60 m/s^2)?
Q) Ball A is thrown straight up with an initial velocity V0 from a cliff of height h above ground, where h is not known. at the same time ball B is dropped from the same cliff. the time of flight of ball B is 1/4 that of ball A. take the upward direction is positive and A) draw a single V vs. t plot for both balls. B) draw a single position vs. time plot for both the balls....
A 5.0 kg bowling ball is dropped from a platform 14.2 m above the ground. Find the kinetic energy of the ball when it hits the ground. Round intermediate answers to 4 significant figures and final answers to 3 significant figures.
A ball has a mass of 0.5kg. Dropped from a cliff top, the ball strikes the sea below at a velocity of 10m/sec. a. What is the kinetic energy of the ball as it is about to strike the sea? b. What was its potential energy before it was dropped? c. From what height was the ball dropped? d. A stone of mass 1 kg also strkes the sea at 10m/sec. Repeat stages a, b and c above to find...
Ball A is thrown horizontally off a cliff, while Ball B is dropped off the edge. Which hits the ground first? Select one: a. depends on how hard Ball A was thrown b. Ball A c. both hit the ground at the same time O d. Ball B
Ball A is dropped from rest from a window. At the same instant, ball B is thrown downward; and ball C is thrown upward from the same window. Which statement concerning the balls after their release is necessarily true if air resistance is neglected? a. All three balls strike the ground at the same time. b. All three balls have the same velocity at any instant. c. At some instant after it is thrown, the acceleration of ball C is...
Two balls of equal size are dropped from the same height from the roof of a building. One ball has twice the mass of the other. When the balls reach the ground, how do the kinetic energies of the two balls compare? a - The lighter one has one fourth as much kinetic energy as the other does. b - The lighter one has one half as much kinetic energy as the other does. c - The lighter one has...

A 1 kg ball and a 10 kg ball are dropped from a height of 10 m at the same time. In the absence of air resistance, O the 10 kg ball will take 10 times the amount of time to reach the ground. O the two balls will hit the ground at the same time. 0 there is not enough information to determine which ball will hit the ground first. O the 10 kg ball will hit the ground...
