Question

If the speed of an object doubles its kinetic energy does what

Answer 1

If the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy. Hope it help!

Answer 2

Step-by-step explanation:

The mathematical expression for the kinetic energy is given by :

`E_k=(1)/(2)mv^2`

Where

m is the mass of the object

v is the velocity with which the object is moving

According to given condition, if the speed of an object doubles, v' = 2v. So, kinetic energy becomes :

`E_k'=(1)/(2)m(2v)^2`

`E_k'=4* (1)/(2)mv^2`

`E_k'=4* E_k`

So, if the speed of an object doubles, its kinetic energy becomes four times. Hence, this is the required solution.
