A 25-Kg Box,sliding on a Rough Horizontal Surface,has a Speed of of 1.2

question 24

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?
