Question

An electric car is being driven through a town at 22 m/s. The kinetic energy of the car is 222640j. Calculate the mass of the car

Answer 1

920 kg

Step-by-step explanation:

You can figure this out using the equation for kinetic energy:

Given:

KE = 222640

v = 22

m = ?

`KE = 0.5mv^2\\222640 = 0.5m(22^2)\\222640=242m\\m=920`
