(1 point) A ball is dropped from a height of 10 feet and bounces. Suppose that each bounce is 5/8 of the height of the bounce before. Thus, after the ball hits the floor for the first time, it rises to a height of 10 ) = 6.25 feet, etc. (Assume g = 32ft/s and no air resistance.) A. Find an expression for the height, in feet, to which the ball rises after it hits the floor for the nth...
(3 points) A ball is dropped from a height of 14 feet and bounces. Suppose that each bounce is 6/8 of the height of the bounce before. Thus, after the ball hits the floor for the first time, it rises to a height of 14 ) = 8.75 feet, etc. (Assume no air resistance.) A. Find an expression for the height, in feet, to which the ball rises after it hits the floor for the nth time: hm = 14(5/8^n...

To test the quality of a tennis ball, you drop it onto the floor from a height of 4.84 m. It rebounds to a height of 2.84 m. If the ball is in contact with the floor for 10.9 ms, what is its average acceleration during that contact?
A soft tennis ball is dropped onto a hard floor from a height of 1.55 m and rebounds to a height of 1.03 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. -Answer is 4.49 m/s (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms. (d) How much did the...
A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.13 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor, in m/s. (b) Calculate its velocity just after it leaves the floor on its way back up, in m/s. (c) Calculate its acceleration (in m/s^2) during contact with the floor if that contact lasts 3.50 ms. (d) How much...
A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.10 m. (Assume that the positive direction is upward. Indicate the direction of velocities and accelerations with the sign of your answer.) (a) Calculate its velocity (in m/s) just before it strikes the floor. (b) Calculate its velocity (in m/s) just after it leaves the floor on its way back up. (c) Calculate its acceleration (in m/s2) during...
suppose that you drop a ball from a window 50 meters above the ground. the ball bounces to 50% of its previous height each bounce. if the ball continues to bounce in this manner how far will it have travled up and down from the time it was dropped from the winfow until the 25th bounce?
A ball is thrown up 90 feet in the air. it comes down, bounces, and then rises up to a height of 81 feet. Then it falls to its second bounce, and so on. Each time it falls, it bounces back to 90% of its previous height. (a) How high does the ball rise before the 30th bounce? (Please read the question carefully. If the question read “How high does the ball rise before the second bounce?” the answer would...
: I drop a tennis ball from a height of h = 5.52 m above an unrealistically huge pile of thick shaving gel. The ball plunges to a depth of d = 18.0 m in the gel before stopping in the gel, at some unknown distance above the floor. a) What is the magnitude of the ball's acceleration while it's falling through the air? b) Calculate the ball's impact speed v (its speed just before it hits the gel). c)...
