Dayton Salazar · Answer 1

F = ma, where m is the mass of the body and a its acceleration.

So F = 39x7.8 = 280.8 N

Guillermo Duarte · Answer 2

To determine the force exerted by the boy in the box, we use Newton's second law of motion. It is expressed as Force = (m) (a) where m is the mass and a is the acceleration. We calculate as follows:

F = m a

F = 39 kg (7.8 m/s^2)

F = 304.2 N
