A 200-lb block is sliding along a horizontal plane at 4 ft/s when a force P is applied on it as shown. The magnitude of P varies according to the relation P = 200t Ib where t is in sec. Find the velocity of the block 2 sec after P is applied. Neglect friction. Use Impulse-Momentum Method and draw the momenta and impulse vectors.
