Question

is velocity is doubled and mass is reduced to 1/4 then initial valuy of kinetic energy becomes​

Answer 1

Answer:

if mass doubled then kinetic energy also gets doubled.. 2..if velocity doubled with constant mass then kinetic energy becomes 4 times the initial kinetic energy..

Answer 2

Answer:

k.e will remain same

Explanation:

as we know

k.E =1/2mv2

1/2 ×1/4 M × (2v)2

1/2 × 1/4M ×4V2

by canceling 4 out we get

k.e ' =1/2Mv2
