🤓 Based on our data, we think this question is relevant for Professor Keister's class at UB.

Which has more kinetic energy, a 1400 kg car moving at 115 km/h or a 12,000 kg truck moving at 38 km/h?

**Concept:** Kinetic Energy.

We are going to calculate the kinetic energy of car and truck using this equation:

**KE = 1/2 mv**^{2}

then compare the energies of the car and the truck.
