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

Solution: 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?

Problem

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?

Solution

Concept: Kinetic Energy.

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

KE = 1/2 mv2

then compare the energies of the car and the truck.
