Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

A roller 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?

Answer 1

answer (c) 22000 J
1/2×2000kg×22ms
=22000 J

Answer 2

Kinetic energy of the car is 484000 Joules.

Step-by-step explanation:

It is given that,

Mass of the car, m = 2000 kg

Speed of the car, v = 22 m/s

We need to find the kinetic energy of the car. The formula of kinetic energy is given by :

`E=(1)/(2)mv^2`

`E=(1)/(2)* 2000* 22^2`

E = 484000 J

So, the kinetic energy of the car is 484000 Joules. Hence, this is the required solution.
