Answer:

v = 5.6 m/s

Step-by-step explanation:

Given,

The mass of the car, m = 1500 kg

The kinetic energy of the car, K.E = 23,500 J

The kinetic energy of the of an object is given by the relation,

K.E = ½ mv²

Substituting the given values in the equation,

23,500 = ½ x 1500 x v²

v² = 23500/ 750

= 31.33

v = 5.6 m/s

Hence, the K.E of the car is, v = 5.6 m/s
