Question

The kinetic energy acquired by a mass m in travelling a certain distance d starting from rest under the action of a constant force is directly proportional to

• A. $\sqrt{m}$
• B. Independent of m
• C. $\frac{1}{\sqrt{m}}$
• D. m

Answer 1

The correct option is B

Independent of m

Kinetic energy acquired by the body

= Force applied on it $\times$ Distance covered by the body

$K.E=F\times d$

If F and d both are same then K.E. acquired by the body will be same
