Question

8. The kinetic energy that a body acquires when it falls
freely for a time t varies directly with the square of
t for a given mass. For bodies of different masses
for a given value of t, the kinetic energy varies
directly as the mass. The kinetic energy of a body of
mass 5 kg which is under free fall for 10 seconds is
25 kilojoules. Find the kinetic energy of a body with
mass 2.5 kg. Which is under free fall for 3 seconds
(in kilojoules)
(A) 102.5 (B) 1.175 (C) 125 (D) 1.125​
