Two bullets have masses of 3.0 g and 6.0 g respectively. both are fired with a speed of 40.0 m/s.(a) which bullet has more kinetic energy? (b) what is the ratio of their kinetic energies?

(a) The bullet with a mass of 6.0 g

(b)

Explanation:

(a) Kinetic energy is defined as:

So, we have:

The bullet with a mass of 6.0 g have more kinetic energy

(b) We have and . So:

Replacing (1) and (2) in (3):
