To find the velocity of the car, we can use the formula for kinetic energy:
KE = 0.5 * m * v^2
Where: KE is the kinetic energy m is the mass of the car v is the velocity of the car
Given: Mass of the car, m = 2000 kg Kinetic energy, KE = 80,000 J
Plugging in the values into the formula, we have:
80,000 = 0.5 * 2000 * v^2
Simplifying the equation:
80,000 = 1000 * v^2
Dividing both sides by 1000:
80 = v^2
Taking the square root of both sides:
v = √80
v ≈ 8.94 m/s
Therefore, the velocity of the car is approximately 8.94 m/s.
