Question

If a particle of mass m moving with velocity $v_1$ is subject to an impulse $I$ which produces a final velocity $v_2$, then $I$ is given by :

• A. $m(v_1-v_2)$
• B. $m(v_1+v_2)$
• C. $m(v_2-v_1)$
• D. $\frac{m(v_2^2-v_1^2)}{2}$

Answer 1

The correct option is C $m(v_2-v_1)$

Impulse is equal to the change in momentum caused by the force.
$I=m\times v_2-m\times v_1$
