A 1600 kg car travels at a speed of 10.5 m/s. What is its kinetic energy? Assume that air resistance is negligible.

KE= 1/2 m v^2

To calculate the kinetic energy of an object, you need to use the formula:

Kinetic Energy = 1/2 * mass * velocity^2

In this case:
Mass of the car (m) = 1600 kg
Velocity of the car (v) = 10.5 m/s

Now, plug these values into the formula:

Kinetic Energy = 1/2 * 1600 kg * (10.5 m/s)^2

Square the velocity first:

Kinetic Energy = 1/2 * 1600 kg * (110.25 m^2/s^2)

Multiply the mass and the squared velocity:

Kinetic Energy = 1/2 * 1600 kg * 110.25 m^2/s^2

Finally, calculate the result:

Kinetic Energy = 88,200 Joules

Therefore, the kinetic energy of the car is 88,200 Joules.
