Question

The average car has a mass of about 1500 kg, and travels at about 30 m/s when it's on the highway; how much
kinetic energy does the average car have when driving at highway speed?

Answer 1

Answer:

675,000 Newtons.

Explanation:

Kinetic Energy = 1/2 * m * v^2

where m is mass and v is velocity.

so,

KE = 1/2 * 1500kg * (30m/s)^2 = 675,000 N or 675kN
