Question

5. When the speed of a particle is doubled, the ratio of its kinetic energy to its momentum
a) remains same
2 b) becomes doubled
c) becomes half
) becomes four times​

Answer 1

Answer:

d becomes 4 times

this question can come in to exams

in 1 m

from the chapter work and energy

Answer 2

Answer:

Kinetic energy = 1/2 mv^2

Speed doubled = 2v

kE = 1/2 m (2v)^2

= 1/2 m 4 v^2

= 4 {1/2m v^2}

= 4 KE

d) become four times
