Answer to Question #161045 in General Chemistry for joseph rowland

Question

A 1643 kg

car is traveling down the road at 94.2 km/h.

While traveling at this rate of speed, what is the kinetic energy of this vehicle in kilojoules?

Answer 1

Mass = 1643 kg

Velocity = 94.2 km/h

Kinetic energy = (1/2)×Mass×(velocity)²

= (1/2)×1643 kg×94.2 km/h

= 7289695.26 Joul

≈ 7289.695 kilojoules

Hence, the kinetic energy of this vehicle = 7289.695 kilojoules
