a 1555 kg car is traveling down the road at 100.2 km/h. while traveling at this rate of speed, what is the kinetic energy of this vehicle in kilojoules?

Answer :

The kinetic energy of the car traveling at 100.2 km/h is approximately 619.31 kilojoules.To calculate the kinetic energy of a moving object, we use the formula:

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

First, we need to convert the speed from km/h to m/s:

100.2 km/h = 100.2 * (1000 m / 3600 s) = 27.83 m/s (rounded to two decimal places)

Now we can substitute the values into the formula:

KE = (1/2) * 1555 kg * (27.83 m/s)^2

Calculating the kinetic energy:

KE = (1/2) * 1555 kg * (27.83 m/s)^2

KE ≈ 619,309.96 joules

To convert the kinetic energy to kilojoules, divide by 1000:

KE ≈ 619.31 kilojoules

Therefore, the kinetic energy of the car traveling at 100.2 km/h is approximately 619.31 kilojoules.
