Question

State newton second law of motion and drive the expression for it.

Answer 1

Newton's second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.

derive:-

F=km(v-u)/t
F=kma. {as (v-u)/t=a}
F=ma. {as k is proportional constant &
k=1}
