Question

If a body has velocity 10 m/s and a mass 2 kg, then find the kinetic energy of the body.

10
20
15
18

hint Hint:

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

The correct answer is: 20

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

where m= mass and v= velocity

K.E= $1 half cross times 2 cross times 10 squared equals 100 space J$
