A2.00 kg box slides on a rough, horizontal surface, hits a spring with a speed of 1.90 m/s and compresses it a distance of 10.0 cm before coming to rest. determine the force constant (in n/m) of the spring, if the coefficient of kinetic friction between the block and the surface is μk = 0.660.

Explanation:

Given

mass of box

speed of box

distance moved by the box

coefficient of kinetic friction

Friction  force

Kinetic Energy of box will be utilize to overcome friction and rest is stored in spring in the form of elastic potential energy

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
