You push a box across the floor with a force of 30 n. you push it 15 meters in 8 seconds. how much work did you do? how much power did you use? pl answer both parts

Work = (force) x (distance)

Work = (30 N) x (15 m)

Work = 450 Joules

Power = (work done) / (time to do the work)

Power = (450 Joules) / 8 seconds)

Power = 56.25 watts

an electric circuit

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
