Question

A bullet of mass 15kg has a speed of 20m/s what is its kinetic energy

Answer 1

Answer:

3000J

Explanation

mass =15kg ,velocity =20m/s

Kinetic energy =1/2mv^2

1/2*15(20)^2

3000j

Answer 2

Answer:

It's kinetic energy is 3000 J

Explanation:

Given data:-

Mass m = 15 kg

Speed v = 20 m/s

Solution:-

Kinetic energy K.E.

= 1/2 mv²

= 1/2 × 15 × 20 ×20

= 3000 J
