Acar moving with a velocity of 20 meters/second has 1.8 × 105 joules of kinetic energy. what is the mass of the car? a.) 4.6 × 102 kilograms b.) 9.0 × 102 kilograms c.) 1.0 × 103 kilograms d.) 1.2 × 103 kilograms

The correct answer is .

Explanation:

The expression for the kinetic energy is as follows;

Here, m is the mass of the object and v is the velocity.

It is given in the problem that A car moving with a velocity of 20 meters/second has of kinetic energy.

Calculate the mass of the car by rearranging the above expression.

Put and v= 20 m/s.

Therefore, the correct option is (B).

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
