A body of mass 2 kg is moving along the north-east direction with a speed $22$ m/s. A force of 0.2 N is applied on the body due west for 20 s. The final velocity of the body is:

Options:

Answer:

Solution:

$u = (2 i + 2 j)$ m/s, $a = - 0.1 i$ $m / s^{2}$ ; at $t = 20$ s the $x$ -component is $2 - 2 = 0$ , leaving $2 j$ : 2 m/s due north. Option C.
