Question

PLEASE HELP !!

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

Step-by-step explanation:

It is given that

The kinetic energy of Mr. Thomson’s prius, K = 641300 J

He is moving with a velocity, v = 22 m/s

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

Due to his motion, a kinetic energy will possess by him. The mathematical form of kinetic energy is given by :

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

Solving for m

`m=(2K)/(v^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.
