Question

A man hits a golf ball (0.2 kg) which accelerates at a rate of 20 m/s 2 . What amount of force acted on the ball?

Answer 1

force=mass×accelaration
=0.2×20=4N

Answer 2

Given: Mass of the ball = 0.2kg

Acceleration of the ball = 20m/s²

To Find: Force acting on the ball

Solution:

Newton's Second Law is stated as "The time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it."

According to this law, the relation between the force and acceleration of an object can be defined.

F = ma, where F is the force acting on the body, m is the mass of the body, and a is the acceleration of the body.

Force acting on the ball = Mass of the ball x Acceleration of the ball

                                        = 0.2 x 20

                                        = 4N

Therefore, the force acting on the ball is 4Newtons.
