their ratios would be 2:3
impraneethgoud:
how?
coz kinetic energy is directly dependent on velocity

hey here is ur answer
KE 1=1/2.m.v1^2
KE 2=1/2mv2^2
KE1/KE2=half and mass will be cancelled out
=>4v^2/9v/2
v^2 cancel out
4:9
KE 1=1/2.m.v1^2
KE 2=1/2mv2^2
KE1/KE2=half and mass will be cancelled out
=>4v^2/9v/2
v^2 cancel out
4:9
but energy is directly dependent on velocity.
send me the picture of the answer on a paper
