Question

A person carries a load of 50kg on his head. What force does he need to lift the load??

Answer 1

Answer:

He needs a force of 490 N to lift the load.

Explanation:

The mass of the load, m = 50 Kg

The acceleration due to gravity of earth, g = 9.8 m/s²

The force with which the earth attracts the load,

F = mg

F = 50 × 9.8

F = 490 N

The person will need to apply this amount of force but in the opposite direction of the force of gravity.
