Question1

Find out the coefficient of kinetic friction between a 3.15 kg block and horizontal surface on which it rests if an 82.0 N/m spring must be stretched by 5.90 cm to pull it with constant speed. Suppose that the spring pulls in the horizontal direction.

Question2

A girl on a sled coasts down a hill. Her speed is 7.8 m/s when she reaches level ground at the bottom. Coefficient of kinetic friction between the sled's runners and the hard, icy snow is 0.047, and the girl and sled together weigh 635 N. How far does sled travel on level ground before coming to rest?

Question3

A net torque of magnitude 500 Nm is exerted on the rotor of an electric generator for 29 s.

What is magnitude of the angular momentum of the rotor at the end of 29 s if it was initially at rest?

Answer in units of kgm2/s
