Question

When the momentum of body is increased

by three times, its K.E. becomes :

(a) Twice (b) Half

(c) Four times (d) Nine times​

Answer 1

Answer:

(d) Nine times is the answer.

Explanation:

Kinetic energy = 1/2 mv square

p= mv

So, K.E. 1/2(p) square

When p , momentum is increased by three times,

K.E.= 1/2 ( 3p) square

K.E. = 1/2( 9p) square

K.E. =9 { 1/2 ( p) square }

Hence 9 times is the answer.
