Step 1

Part A:

Newton’s Laws of motion:

First Law : The body which is at rest remains to be at rest and the body which is in uniform motion(constant velocity) remains to be in uniform motion until some external force acts on it.

Second Law: Force acting on the body is equal to rate of change of momentum. Rate of change of momentum gives the instantaneous force acting on the body.

Third Law: For every action there will be an equal and opposite reaction .Forces and couples will occur in action reaction pairs.

Step 2

According to Newton’s second law we have

Step 3

From equation 1 ,if force acting...
