What is speed of the lock after it has fallen 2m from rest

Reference no: EM13339906

A 8kg block is attached to a light rope that passes over a uniform disk-shaped 4kg pully of radius 0.6m without slipping. On the other side of the puly the rope is attached to a light unstreched spring with a stiffness of 17.5N/m. (g=10.0m/s^2)

a) what is the speed of the lock after it has fallen 2.0m from rest.

b) waht is the tension on the rigt side of the rope when the block has fallen 3.0m form rest.

c) what is the magnitude of the net torque acting on the pully at the instant in b (ie. when the block has falled 3.0m form rest)
