Question

If kinetic energy increases to 16 times then the velocities should be increased to ( how many ties ) ?

Answer 1

4times the velocity should be increased

Answer 2

hey mate here is your answer

KE=1/2mv²

KE' = 16/2mv'² = 8mv'²

=> 8mv'²= 1/2mv²

=> 16mv'²= mv²

=> 16v'² = v²

=> 4v' = v

=>so, v = 4v'

So,Velocity increased by 4 times

hope it may help you
