Question

A car with a mass of 600 kg is traveling at a velocity of 10 m/s. How much kinetic energy does it have?

The car has
J of kinetic energy

Answer 1

The car has 30,000 J of kinetic energy.

Answer 2

Answer: 30000 joules

Step-by-step explanation:

Mass of car = 600kg

Velocity of car = 10m/s

Kinetic energy = ?

Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass M and velocity, V

Thus, Kinetic energy = 1/2 x mv^2

= 1/2 x 600kg x (10m/s)^2

= 0.5 x 600kg x (10m/s)^2

= 300 x (10m/s)^2

= 300 x 100

= 30000 joules

Thus, the car travels with a kinetic energy of 30000 joules
