A 25-Kg Box, Sliding on a Rough Horizontal Surface, Has a a Speed

question 30

Short Answer

A 2.5-kg box, sliding on a rough horizontal surface, has a speed of 1.2 m/s when it makes contact with a spring (see the figure). The block comes to a momentary halt when the compression of the spring is 5.0 cm. The work done by the friction, from the instant the block makes contact with the spring until is comes to a momentary halt, is -0.50 J. (a) What is the spring constant of the spring?
(b) What is the coefficient of kinetic friction between the box and the rough surface?
