Problem
A 1.0 kg block rests on a horizontal table and is attached to an ideal spring (spring constant 50 N·m⁻¹) fixed to a wall. The coefficient of kinetic friction between the block and the table is 0.15. The block is pulled 0.12 m to the right of equilibrium and then released from rest, immediately beginning to slide. Taking rightward as positive, calculate the magnitude and direction of the block’s instantaneous acceleration just after release.
