Question

14. When the speed of a particle is doubled, the ratio of
its kinetic energy to its momentum
(a) remains the same (b) gets doubled
(c) becomes half (d) becomes 4 times

​

Answer 1

Answer:

(d) become 4 times

Explanation:

K.E = 1/2 (mv)^2

when we double speed , velocity becomes double..

therefore., new K.E. becomes 4 × 1/2 (mv)^2

hope this helps u...☺✌

Answer 2

Answer:

(b) gets doubled

Explanation:

This is correct answer
