Question

I need help on this science question

Answer 1

C

Step-by-step explanation:

The kinetic energy of a body is the energy due to the motion of a body. It is mathematically given as;

Kinetic energy =
`(1)/(2)` m v²

m is the mass of the body

v is the velocity

Now, let us find the K.E from the given choices;

Option C will have the greatest kinetic energy;

mass = 0.14kg , v = 40m/s

Kinetic energy =
`(1)/(2)` x 0.14 x 40² = 112J
