Work, Power, and Energy. Bob pushes a box across a horizontal surface at a constant speed of 1 m/s. If the box has a mass of 30 kg, find the power Bob supplies given the coefficient of kinetic friction is 0.3.

Which formula would I use and how would the coefficient of kinetic friction come into play? Thank you in advance!

90 watts

okay bye

v=ir = 3x15 =45 v

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
