Answer 2

Calculation of Kinetic Energy

To calculate the kinetic energy of an object, we can use the formula:

Kinetic Energy (KE) = (1/2) * mass * velocity^2

Given that the mass of the car is 1 ton (or 1000 kg) and its velocity is 15 m/s, we can substitute these values into the formula to find the kinetic energy.

KE = (1/2) * 1000 kg * (15 m/s)^2

Calculating this expression, we find:

KE = 0.5 * 1000 kg * (225 m^2/s^2)

Simplifying further:

KE = 112500 J

Therefore, the kinetic energy of the car with a mass of 1 ton and a velocity of 15 m/s is 112500 Joules.
