A rubber ball keeps on bouncing back to 2/3 of the height from which it is dropped. Can you calculate the fraction of its original height that the ball will bounce after it is dropped and it has bounced four times without any hindrance ?
16/81
1 bounce, results in =2/3 of the original height 4 bounces result in =(2/3)^4 =16/81 or original height
I dropped a ping pong ball at the end of a curvy long hole in the ground. I want to get it out but I can't stick my hand in it since it won't fit. What can you do to help me get it out without digging a hole?
In Africa, if you drop a steel ball weighing five pounds from a height of 5 feet, will it fall more rapidly through water at 20 degrees Fahrenheit or water at 40 degrees Fahrenheit. Or will it make no difference?
A ball is thrown upwards with speed v from the top of a tower and its reaches the ground with speed 3v. What is the height of the tower?
A ball is dropped vertically upon a slope. What type of progression do the distances between each consecutive bounce?
Assumptions: -Ignore air resistance -Assume all collisions to be perfectly elastic
How can you throw a ball as hard as you can and have it come back to you, even if it doesn't bounce off anything? There is nothing attached to it, and no one else catches or throws it back to you?
