Question

a body of mass 2 kg is moving with an acceleration of 50cm/s .calculate the force acting on it

Answer 1

Firstly we will convert 50 cm/s in m/s
1 m =100 cm
Therefore 50 /100 = 0.5 m/s
Force = mass *acceleration
= 2 * 0.5
= 1 N

Answer 2

Answer:

Force acting on the body.

Explanation:

Newton's Second Law of motion: According to the Newton's second law, it state that the time rate of change of momentum of the body is equal to the magnitude and the direction of force acting on it. It is written as;

               F = ma   .....(1)

Given:

m = 2 kg

a = 50 cm/s²

  = 0.5 m/s²

using equation (1) we have,

F = ma

F = 2 ×0.5

F =1 N

Result:

Hence force acting on body is equal to 1 N
