A body of mass 6 kg moves in a straight line according to equation $x = t^{2} - 40 t$ where x denotes the distance in metre and t the time in seconds. The net force on the body at $t = 4$ second is

Options:

Answer:

Solution:

$x = t^{2} - 40 t \Rightarrow v = \frac{d x}{d t} = 2 t - 40 \Rightarrow a = \frac{d v}{d t} = 2 m/ s^{2}$ (constant).

$F = ma = 6 \times 2 = 12 N$ .
