Ghoulie · Answer 1

86.4 N downward

Explanation:

Force: This can be defined as the product of mass and acceleration of a body.

The S. I unit of Force is Newton (N).

The Expression of force is given as,

F = ma ... Equation 1

Where F = force of the parachute harness, m = mass of the skydiver, a = acceleration of the skydiver.

Given: m = 72 kg, a = 1.2 m/s²

Substitute into equation 1

F = 72 (1.2)

F = 86.4 N down ward.

Hence the force on the parachute harness = 86.4 N downward
