Ramiro Baxter · Answer 1

Since the ball is in motion, the energy can be calculated by the equation for kinetic energy (KE) which is,

KE = 0.5mv²

Substituting the known values from the given,

KE = 0.5 (2.1 kg) (30 m/s) ²

Simplifying the equation will give us an answer of,

KE = 945 J

Thus, the ball has an energy of 945 J.
