Coefficient of Restitution (cor) of colliding bodies describes how elastic or inelastic a collsion is. But, most internet sources (the golf-related sites) and http://en.wikipedia.org/wiki/Coefficient_of_restitution" , describes cor as a property of a particular object. Isn't this wrong? The cor...
Hi there,
I have been struggling with this problem for a while. It's an A-Level Mechanics problem.
A smooth groove in the form of a circle of radius a is carved out of a horizontal table. Two small spheres, A and B, lie at rest in the groove at opposite ends of a diameter. At time t = 0...
[SOLVED] Coefficient of restitution help
Homework Statement
A light elastic string AB, of natural length 0.5m and modulus of elasticity 12N, has a particle of mass 0.3 kg attached to B. The end A is attached to a fixed point at a distance of 0.7m above a horizontal table. The coefficient of...
Homework Statement
coursework - I will be varying the temperatures of steel ball bearings as they drop onto a metal plate, with the bounce heights, i can work out the coefficient of restitution. however, i need help on the theory behind how temperature will actually effect the coefficient...
[SOLVED] coefficient of restitution
Homework Statement
My book defines the coefficient of restitution as
\epsilon = \frac{|v_2-v_1|}{|u_2-u_1|}
but does not really explain what u_1, u_2, v_1, and v_2 mean. Those terms are all scalars since the coefficient of restitution only "works" in one...
Coefficient of Restitution? PLEASE HELP!
Homework Statement
Two balls of equal mass moving with the speed of 3 m/s, collide head on. Find the speed of each after impact if the coefficient of restitution is 1/3.
Homework Equations
e=(v2-v1)/(u1-u2)
v2= velocity after impact of object 2
v1=...
Homework Statement
i'm retaking a test question for half credit and this is the 3rd part to the question. i know the velocities are correct because the teacher gave us the answers.
this SHOULD be simple... but okay.. (velocity) V1 = 20ft/s, V2 = 0ft/s. after the collision V1` = 16ft/s...
I'm developing a 2-dimensional physics simulator (it includes gravity, electric force, and collisions as of now, between spherical objects of varying masses, charges, and radii). I'm trying to improve my collision algorithm, though, and I'm not sure how to handle coefficients of restitution...
Hi all,
I am trying to find the coefficient of restitution in this example:
Block m1=2 kg is pushed with initial velocity v=7 m/s for distance
d = 4 meters towards a wall. Kinetic friction b/w floor and block is mK = 0.4. The block rebounds off the wall and travels distance
d2 = 1 m before...
