Question

I need help on this science question

Answer 1

Answer:

C

Explanation:

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

 Kinetic energy  = $\frac{1}{2}$ 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  = $\frac{1}{2}$ x 0.14 x 40²   = 112J
