Given,

Mass= 50kg

Force= ?

We know that,

F= m×a

F= 50 × 9.8 (Since acceleration due to gravity on earth is 9.8 m/s²)

F = 490 N

Given,

m = 50 kg

g = 9.8 m/s²

The force does he need to lift the load.

F = mg

F = 50 x 9.8

F = 490 N

The person will need to apply this amount of force, in opposite direction.
