Question

What is the kinetic energy of a car that has a mass of 1500 kg and is moving at 60 m/s?

Answer 1

Given: A car of mass $1500 kg$ is moving at $60 m/s$

To find: The kinetic energy of the car.

Solution:

The formula for kinetic energy is given by,

$K=\frac{1}{2}mv^{2}$

⇒ $K = \frac{1}{2}*1500*60^{2}$

⇒ $K=2.7*10^6 J$

Final answer:

The Kinetic Energy of the car is $2.7*10^6$.

Answer 2

*Given* : A car of mass 1500 kg moving with a speed of 60 m/s

*To Find* : The Kinetic Energy of the car

*Solution* :

Formula of Kinetic Energy :

KE = 1/2 mv^2

m : mass of the car

v : Speed of the car

KE = 1/2 x (1500) x (60)^2

= 27 x 10^5 Joules

*Final Answer* : The Kinetic Energy of the car is *27 x 10^5 Joules*
