Question

The velocity of an object becomes doubled then its kinetic energy will be

Answer 1

Answer:

the kinetic energy will become 4 times

Explanation:

we know,

K.E.= (1/2)mv^2

initial KEi = (1/2)mv^2

new KEf when velocity is doubled = (1/2)m (2v)^2

                                                         = (1/2)m(4)v^2

                                                         =4 [(1/2)mv^2]

                                                         =4KEi
