Question

A man is pushing a cart down in slope. Suddenly the cart starts moving faster and he wants to slow it down. What should he do?

Answer 1

Following processes can be followed-
(i) He can pull the cart to apply a reaction force on it. It will
help to slow down the cart and after some time it may stop.
(ii) By going at the opposite side of the cart he can give the
cart the necessary push to slow it down.
In both cases, he’ll be applying reaction force on the cart.
