The coefficient of friction depends upon the properties of the surfaces in contact. What factors do you believe determine the coefficient of friction?
Give examples of materials with a low coefficient of friction and a high coefficient of friction
Explain why you believe these materials would exhibit a low or high coefficient of friction.
A lump of putty with a mass of 0.550 kg and a speed of 0.750c collides head-on and sticks to an identical lump of putty moving with the same speed
A 1.8-kg cylinder (radius = 0.08 m, length = 0.50 m) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is 0.82 m high and 5.0 m long. What is its translational kinetic energy? What is its rotational kinetic ene..
