A Canonball And Marble Roll

I understand the marble won t roll without friction.

A canonball and marble roll.

The point is not to ignore friction entirely then the question is meaningless but in the first case to assume that the friction for the two marbles is constant and for the second case to closer simulate reality by allowing the friction to have different values. 209 334 0333 text upon arrival only for pick up. A cannonball and a marble roll from rest down an incline. It is given by the.

Does the cannonball take more less or the same time as the marble to reach the bottom. Which gets to the bottom first. Is the fraction of the cannonball s kinetic energy associated with translation more than less than or the same as that of the marble. Is the cannonball s a time to the bottom and b translational kinetic energy at the bottom more than less than or the same as the marble s.

Roll out here mister if you need a lttle rest lay me down in marbletown a bone yard is the best there was a bad bull on the railroad tried to put me off his train lay me down in marbletown til the coast is clear again i can hear them a hollerin we got a man down here we got a man down i m gonna flip me a cannonball that won t stop for anyone. It is obvious that the radius of the marble will be smaller than the radius of the cannonball therefore the marble will have smaller rotational inertia than the cannonball and will make more revolutions per second. Acceleration is defined as the rate at which the object velocity changes.
