A man doing push-ups pauses in the position shown in the figure . His mass m = 80 kg.

In push up position:

From hands to waist = 40 cm
From waist to feet = 95 cm
height - heel of foot to ground = 30 cm

Determine the normal force exerted by the floor on each hand.

Determine the normal force exerted by the floor on each foot.
