A block of mass m50kg is attached to a spring with, Ask an Expert

Academics

A block of mass m=5.0kg is attached to a spring with springconstant k=8.0 N/m. The block is pushed so that it compresses thespring and gains speed. At t = 0 the block is releasedat x = -0.75 m with a velocity v = -2.5 m/s

a.) what is the soonest time after t = 0 that the block is atposition x = -0.75?

b.) What is the amplitude of oscillation?

c.) Find the velocity of the block at t =3.0s.
