Question

What is the kinetic energy of a 1500 kg car moving at 15 m/s?​

Answer 1

Answer:

168,750 Joules

Explanation:

Kinetic energy = 1/2 mv²

= 1/2 (1500) (15) (15)

= 168750 J

Answer 2

Answer:

168.750 KJ

Explanation:

The kinetic energy is given by the formula    

K.E = 1/2 mv^2

Plug in the value of mass m = 1500 and v = 15 in this to get

K.E=   1/2 × 1500 × 15 × 15

=  168,750 J

1KJ = 1000J

So, dividing the above value by 1000, we get

168.750 KJ
