Question

at a given instance of time a 12kg rock is observed to be falling with an acceleration of 6.25 m/s2 what is the magnitude and direction of the net force on the rock, what is the magnitude and direction of the gravitational force on the rock and what is the magnitude of the of the force of air resistance acting on the rock?

Answer 1

Answer:

it's F= ma i.e force= mass X acceleration=> 12x6.25=75.00 N is the net force acting downward and gravitational force is acting downwards
