Aroller coaster car is traveling down a track at 22 m/s. the car has a mass of 2000 kg. what is the kinetic energy of the car? a) 22,000 j b) 968,000 j c) 484,000 j d) 44,000 j

The kinetic energy of the car is 484000 J

Explanation:

Given

Velocity = 22 m/s

Mass = 2000 kg

To Find:

Kinetic energy of the car= ?

Solution:

Kinetic energy of the car  is given by

Where

m= mass of the car

v= velocity  

KE = kinetic energy

So, substituting the values

tex]KE = \frac{1}{2}\times(2000*22^2)[/tex]

KE = 484000 J
