Aball of mass 0.4 kg flies through the air at low speed, so that air resistance is negligible. what is the net force acting on the ball while it is in motion?

-3.92 N

Step-by-step explanation:

We are given that

Mass of ball=0.4 kg

Acceleration due to gravity=

Because the ball flies against to gravity

We have to find the net force acting on the ball while it is in motion.

We know that when there is no air resistance then the net  force acts on the ball is equal to weight of ball.

Net force,F =mg

Substitute the values then we get

Hence, the net force acting on the ball while it is on motion=-3.92 N

the answer will be

answer by mimiwhatsup: no. you can report it but you would have to wait for a moderator to approve the request to delete it. hope that .
