A body of mass 2 kg is moving along the north-east direction with a speed $2$ m/s. A force of 0.2 N is applied on the body due west for 10 s. The final velocity of the body is:

Options:

Answer:

Solution:

$u = 2 cos 4 5^{\circ} i + 2 sin 4 5^{\circ} j = (i + j)$ m/s; $a = F / m = - 0.1 i$ $m / s^{2}$ . At $t = 10$ s, $v = (i + j) - i = j$ : 1 m/s due north. Option A.
