Question

Determine the kinetic energy of 8000 Newton’s roller coaster car that is moving with a speed of 20.0 meters/seconds

Answer 1

The kinetic energy of the roller coaster is 1600000 J.

Explanation:

Given:

Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.

Now, we need to find the kinetic energy
`E_(k)` of the roller coaster.

So, Mass of roller coaster (m) = 8000 N.

Velocity of roller coaster (v) = 20.0 m/s.

Now, putting the formula of kinetic energy:

`E_(k) = (1)/(2)* m* v^(2)`

`E_(k)=(1)/(2) * 8000* 20^(2)`

`E_(k)=(1)/(2) * 8000* 400`

`E_(k)=(1)/(2) * 3200000`

`E_(k)=1600000`

Therefore, the kinetic energy of the roller coaster is 1600000 J.
