kinetic energy of a car that’s 1200 KG going 28 m/s

Answer 1

To calculate the kinetic energy of a moving object, you can use the formula:

KE = 0.5 * m * v^2

Where:
KE = kinetic energy
m = mass of the object (in kg)
v = velocity of the object (in m/s)

Given:
m = 1200 kg
v = 28 m/s

Plugging the values into the formula:

KE = 0.5 * 1200 kg * (28 m/s)^2
KE = 0.5 * 1200 kg * 784 m^2/s^2
KE = 600 kg * 784 m^2/s^2
KE = 470400 J

Therefore, the kinetic energy of a car that's 1200 kg going 28 m/s is 470400 Joules.
