A2.5-kg box, sliding on a rough horizontal surface, has a speed of 1.2 m/s when it makes contact with a spring. the block comes to a momentary halt when the compression of the spring is 2.0 cm. the thermal energy generated by friction, from the instant the block makes contact with the spring until it comes to a momentary halt, is 0.5 j (b) what is the coefficient of kinetic friction between the box and the rough surface?
