To determine the velocity of the car, we can use the equation for kinetic energy:
KE = (1/2) * m * v^2
Where: KE is the kinetic energy m is the mass of the car v is the velocity of the car
Given: m = 2000 kg KE = 80,000 J
Substituting the given values into the equation, we have:
80,000 = (1/2) * 2000 * v^2
To solve for v, let's rearrange the equation:
v^2 = (2 * 80,000) / 2000
v^2 = 80
Taking the square root of both sides, we get:
v = √80
v ≈ 8.94 m/s
Therefore, the velocity of the car is approximately 8.94 m/s.
