The kinetic energy of an object of mass m moving with a velocity of 25m
/s the velocity of 25j what is it kinetic energy when the velocity is doubled

KE=1/2MV²
As velocity is doubled as taking M= constant so KE is directly proportional to velocity square so New V'=2V so V'²=(2V) ²=4V²
so KE gets 4 times of initial.
KE'=4KE=4*25=100j
