net work on cart=(92-16.8)*5.6
net work on friction=16.8*5.6
work done by YOU= 92*5.6
You are in the supermarket, pushing a cart with a force of 92 Newtons in the horizontal direction. There is a constant force of kinetic friction operating on the cart of 16.8 Newtons.
Calculate the net work done on the cart, if the cart is displaced 5.6 metres in a straight line.
