In the energy transformation in multiple collisions experiment, if the initial release height is 175 cm and the first rebound height is 155 cm what would you expect to measure as the 5th rebound height?
Homework Answers
let
H = 175 cm
h1 = 155 cm
coefficient of restitution, e = h1/H
e = 155/175
= 0.8857
so,
h2/h1 = e
h3/h2 = e
h4/h3 = e
h5/h4 = e
now use,
(h5/h4)*(h4/h3)*(h3/h2)**(h2/h1)*(h1/H) = e^5
h5/H = e^5
h5 = e^5*H
= 0.8857^5*175
= 95.4 cm <<<<<<<<<<<----------------Answer

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...

Background Info: In this experiment you will observe and analyze elastic and inelastic collisions in one dimension and in two dimensions. You will measure the final momentum of a system after it explodes. You will see how both kinds of collision affect the kinetic energy of a system that consists of two frictionless carts. You will determine the momentum of two carts after they collide when one cart is initially stationary. You will analyze the results qualitatively as well as...

The experiment is about elastic collisions. It is two cars and one of them is on a ramp and the other is down the ramp. The top car (A) will be pushed to collide with the bottom car (B). Regarding the experiment described: Suppose car A starts from a height of 5 cm above the flat glass. Car A has a mass of 100 grams and car B has a mass of 150 grams. 1) How fast will car A...

In the Energy Transformation experiment, suppose that you launch the cart uphill from the bottom of the track with a certain initial speed. You now put in a taller riser block and repeat the experiment using the same initial speed of the cart. How will using a taller riser block affect the maximum distance that the cart travels along the track? Select one: a. The cart will travel a greater distance with the taller block O b. The cart will...

Based on your results. did all of the initial gravitational potential energy convert into kinetic energy? If there is a difference between the gravitational potential energy and the kinetic energy, what do you think caused the difference? Did the angle of the track or the mass of the cart have any effect on the data? Explain What were the sources of error m this experiment? How did your hypothesis compare to your conclusion? Hypothesis in winter ski jumping, how would...

A block has an initial kinetic energy K. If the block moves in the opposite direction with one fifth its initial speed, then what is its new kinetic energy? 4/5 K K/25 -K/5 -K/25 None of the above. A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 9 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction u 0,5. Next. it slides...

A group of students perform the same "Conservation of Mechanical Energy" experiment that you performed in lab by allowing a solid sphere and then a solid cylinder to roll down the ramp. The solid sphere was released from a height of 12.9 cm. From what height hcylinder should the solid cylinder be released so that it has the same speed as the solid sphere when it reaches the bottom of the ramp?
