Solution

The kinetic energy (KE) of an object can be calculated using the formula:

KE = 1/2 * m * v^2

where: m is the mass of the object (in kg) v is the velocity of the object (in m/s)

In this case, the mass (m) of the car is 1120 kg and the velocity (v) is 40 m/s.

Substituting these values into the formula gives:

KE = 1/2 * 1120 kg * (40 m/s)^2

First, square the velocity:

(40 m/s)^2 = 1600 (m^2/s^2)

Then, multiply this by the mass and 1/2:

KE = 1/2 * 1120 kg * 1600 (m^2/s^2) = 896000 Joules

So, the kinetic energy of the car is 896000 Joules.
