A block of mass 2.0 kg is attached to a spring whose spring constant is ?...

A block of mass 2.0 kg is attached to a spring whose spring constant is ? = 8 N/m. The block slides on an incline with θ = 37 . The block starts at rest with the spring unextended before sliding down a distance of 0.5 m down the incline. Assume that µk = 0.20. What is the velocity of the block as soon as it slides 0.5 m down the incline? (Ans: ?? = 1.825 ?/? )
