Answer 1

Answer:

1:16

kinetic energy of the body K= 1/2mv2

for the same mass M, K infinity V2

Given: V1=V and V2=4V

does ratio of kinetic energy =K1/K2=V²1/v²2

. ° .K1/K2=V2/(4v2)=1/6

Answer 2

Answer:

$v1/v2=2/4=1/2\\\frac{K1}{K2}=\frac{1/2mv_{1} ^{2} }{1/2mv_{2} ^{2}} =\frac{v_{1} ^{2}}{v_{2} ^{2}} =\frac{1^{2} }{2^{2} } =\frac{1}{4}$
