A block of mass 2 kg is attached to a spring whose spring constant is ? = 8 N/m. The block slides on an incline with θ = 37o. If the block starts at rest with the spring in relaxed position, what is the work done by the spring on the block if the block has slid a distance of 0.5 m down the incline? Assume μk = 0.45.
