Question

what is the mass of mr. thomson’s prius if his kinetic energy is 641300 J when he is driving at a velocity of 22 meters per second on the highway? please show work

Answer 1

Mass, m = 2650 kg

Step-by-step explanation:

We have,

Kinetic energy of Mr. Thomson’s prius is 641300 J

He is moving with a velocity of 22 m/s

It is required to find the mass of Mr. Thomson’s prius.

Kinetic energy,

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

Plugging all the values, we get :

`m=(2K)/(v^2)\\\\m=(2* 641300)/((22)^2)\\\\m=2650\ kg`

So, the mass of Mr. Thomson’s prius is 2650 kg.
