PLEASE HELP

Answer 1

Answer:

A) Two forces would be acting on the Crate.

B) The normal force acting on the crate is 735 N.

C) The normal force acting on the crate is when on Earth at rest is also 735N.

A)Explanation:

The two forces acting on the crate are Normal force acting upward, and the pseudo force (mass × acceleration) acting downward.

B) Explanation

As we know Normal Force = mass×acceleration

mass = 75 kg

Substituting the values in the above equation, we find

Normal Force = 75×9.8=735 N

C) Explanation

As we know Normal Force or Weight = mass×acceleration due to gravity (g)

Substituting the values in the above equation, we find

mass = 75 kg, acceleration = 9.8 $m/s^2$

Normal Force  at rest = 75×9.8=735 N
