Work Energy And Power Question 54
Question: If velocity of a body is twice of previous velocity, then kinetic energy will become [AFMC 1996]
Options:
A) 2 times
B) $ \frac{1}{2} $ times
C) 4 times
D) 1 times
Show Answer
Answer:
Correct Answer: C
Solution:
Kinetic energy = $ \frac{1}{2}mv^{2} $
K.E. $ \propto $ v2
If velocity is doubled then kinetic energy will become four times.
