Question

If a body has velocity 4 m/s and a mass 3 kg, then find the kinetic energy of the body.

15
16
20
18

hint Hint:

Kinetic Energy = $1 half cross times m cross times v squared$

The correct answer is: 18

Kinetic Energy = $1 half cross times m cross times v squared$

where m =mass and v=velocity

so K.E= $1 half cross times 3 cross times 4 squared equals 24 space J$
