Q.
The figure shows the position $–$ time $(x - t)$ graph of one-dimensional motion of a body of mass $0.4\ kg$ . The magnitude of each impulse is
A) $0.2\ Ns$
B) $0.4\ Ns$
C) $0.8\ Ns$
D) $1.6\ Ns$
Explanation
(c) Impulse $= \ \mathrm{\Delta}P = m\left( V_{f} - V_{i} \right) = 0.4\left\lbrack 1 - ( - 1) \right\rbrack = 0.8\ Ns$
