Question

A car is traveling at a speed of 20m/s and has a mass of 1200kg how much kinetic energy does it have

Answer 1

Step-by-step explanation:

The formula for Kinetic Energy is

`KE=(1)/(2)mv^2`. Filling in:

`KE=(1)/(2)(1200)(20)^2` It looks like we only need 1 significant digit here but I'll give you 2 and you can round how you want.

KE = 2.4 × 10⁵ J
