PLEASE HELP <3

Answer 1

Answer:

The mass of Mr. Thomson’s prius is 2650 kg.

Explanation:

We are given with, the 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.

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

$K=\dfrac{1}{2}mv^2$

Solving for m

$m=\dfrac{2K}{v^2}$

Plugging all the values, we get :

$m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg$

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