Calculate the kinetic energy of a car with a mass of 475kg rolling down a hill at a speed of 5m/s.

Answer: 5937.5 joules

Explanation:

kinetic energy of car K. E = ?

Mass of car M = 475kg

speed of car V = 5m/s

The Kinetic energy of an object is the energy possessed by the moving object, and it depends on its mass and speed.

Thus, K. E = 1/2 x mass x velocity^2

K. E = 1/2 x 475kg x (5m/s) ^2

K. E = 0.5 x 475 x 25

K. E = 5937.5 joules

Thus, the kinetic energy of a car is 5937.5 joules
