A 2.4 kg breadbox on a frictionless incline of angle %u03B8 =43 is connected, by a cord that runs over a pulley, to a light spring of spring constant k= 120 N/m, as shown in the figure below. The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless.

(a) What is the speed of the box when it moves 10 cm down the incline?

m/s

(b) How far down the incline from its point of release does the box slide before momentarily stopping?
