Solution

Q.
A spherical body of mass 2 kg starting from rest acquires a kinetic energy of 10000 J at the end of 5 second. The force acted on the body is ______ N. [2023]

Ans.
(40)

$\frac{1}{2} \times 2 \times v^{2} = 10000 \Rightarrow v = 100 m/s$

$\Rightarrow v = a t = a \times 5 = 100 \Rightarrow a = {20 m/s}^{2}$

$F = m a = 2 \times 20 = 40 N$
