5. A rubber ball dropped on a hard surface takes a sequence of bounces, each one 3/5 as high as the preceding one. If this ball is dropped from a height of 15 feet, what is the total distance it has traveled after it hits the surface the fifth time? The answer is 54 and 21/125 ft, but why? A rubber ball dropped on a hard surface takes a sequence of bounces, each one 3/5 as high as the preceding...
5. A ball is dropped from rest from the top of a building of height h 100.25 m friction, find (a) How long does it take the ball to hit the ground? (b) What speed (b) What speed does the ball travel the instant before it hits the ground?
1. A beach ball with a mass of 500 g is dropped from a height of 5 m. The wind is blowing and exerts a steady 0.8 N force horizontally on the ball. ?-? 0.8U wind force 5 m time? ? distance? ? Suppose the ball is at rest when it is dropped. (a) How much time goes by before the ball hits the ground? (b) Where does the ball hit the ground? Give the distance measured horizontally from where...
A ball is dropped from a height of 3m and bounces on the ground. At the top of each bounce, the ball reaches 60% of it's previous height. Calculate the total distance travelled by the ball when it hits the ground the fifth time.Could you please check over my answer?Sn= a(r^n-1) -------- r-1 = 3(0.6^5 -1 ) ----------- 0.6-1 = 6.9168That is the answer i get, but at the back of the book the answer is 10.8m. Can you correct...
please explain the answer 2) A ball is dropped from rest at a height H. At height h (below H) the ball bounces off a surface with no loss in speed. The surface is tilted at 45°, so the ball bounces off horizon- tally. Derive an expression for the distance the ball travels in the horizontal direction. Plot the distance traveled in the horizontal direction as a function of h where h varies between O and H. 3) Imagine an...
