Answer 2

Answer:

Newton’s second law of motion states that the force exerted by a body is directly proportional to the rate of change of its momentum. For a body of mass ‘m’, whose velocity changes from u to v in time t, when force ‘F’ is applied.

F∝ Change in momentum / Time

F∝ (mv−mu)/t

F∝m(v−u)/t

⇒F∝ma⇒F=kma(∵a=(v−u)/t)

⇒F=ma(∵k=constant=1)
