As shown in the figure below, a box of mass m = 17.0 kg is released from rest (at position A) at the top of a 30.0 frictionless incline. point of release The box slides a distance d = 4.50 m down the incline before it encounters (at position B) a spring and compresses it an amount x = 0.280 m (to point C) before coming momentarily to rest. Using energy content, determine the following. (a) the speed (in m/s) of the box at position B VB = m/s (b) the spring constant (in N/m) k = N/m (c) the physical quantity that is constant throughout the process O kinetic energy O elastic potential energy O gravitational potential energy O total energy 6:11 PM
