An object of mass 16 kg has 3200 J of kinetic energy. What will be its velocity?

Text Solution

Verified by Experts

The correct Answer is:
The velocity of the object will be `20ms^(-1)`.

Here, `m=16kg,E_(k)=3200J,v=?`
`E_(K)=(1)/(2)mv^(2)`
`therefore 3200=(1)/(2)xx16v^(2)`
`therefore v^(2)=(3200)/(8) therefore v^(2)=400 therefore v=20ms^(-1)`
