प्रश्न
A man is pushing a cart down a slope. Suddenly the cart starts moving faster and he wants to sloyy it down. What should he do?
उत्तर
Man can do following things:
- He can start pulling the cart instead of pushing it in order to balance the downward
force due to gravity. - He can go the other side by moving himself very fast in the direction of motion and try to slow down the speed of cart by giving an opposite force to the moving cart.
