A CAR 250KG HAS A VELOCITY OF 10M/S. CALCULATE THE KENETIC ENERGY OF THECAR
KE = 1/2 mv^2

.... and by the way it is in Joules
To calculate the kinetic energy of a car, you need to use the formula:
Kinetic Energy (KE) = (1/2) * mass * velocity^2
Given:
Mass of the car (m) = 250 kg
Velocity of the car (v) = 10 m/s
Now we can substitute the values into the formula:
KE = (1/2) * m * v^2
= (1/2) * 250 kg * (10 m/s)^2
First, let's calculate the velocity squared:
v^2 = 10 m/s * 10 m/s
= 100 m^2/s^2
Now, substitute the calculated value of v^2 into the formula:
KE = (1/2) * 250 kg * 100 m^2/s^2
Multiply the mass and the velocity squared:
KE = 0.5 * 250 kg * 100 m^2/s^2
= 0.5 * 25000 kg⋅m^2/s^2
Finally, calculate the result:
KE = 12500 kg⋅m^2/s^2
Therefore, the kinetic energy of the car is 12500 kg⋅m^2/s^2.
