The position-time graph of a body of mass \( 2 \mathrm{~kg} \) is as shown in figure. What is the impulse on the body at
\( \mathrm{P} \)
\( t=4 \mathrm{~s} \) ?
W
(1) \( 2 / 3 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \)
(2) \( -2 / 3 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \)
(3) \( 3 / 2 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \)
(4) \( -3 / 2 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \)
