A child pushes horizontally on a box of mass m which moves with constant speed v across a horizontal floor. The coefficient of f riction between the box and the floor is μ. At what rate does the child do work on the box?
1 answer:
Answer:
Explanation:
Given
mass of box is m
speed of box is v
coefficient of friction
Box is moving at a constant speed i.e. Net Force on box is zero
i.e. Frictional Force and Force Applied are Equal
The Rate at which power is generated is
