To calculate the kinetic energy of each car before braking, we need to know the mass and velocity of each car.

1. Determine the mass of the car: This can be obtained from the vehicle's specifications or by using a scale capable of measuring the weight of the car. The weight can then be converted to mass by dividing it by the acceleration due to gravity (approximately 9.8 m/s²).

2. Measure the velocity of the car: This can be done using a speedometer or by timing how long it takes the car to cover a known distance. Make sure to measure the velocity just before the car starts braking.

3. Use the kinetic energy formula: The kinetic energy (KE) of an object is given by the formula KE = 0.5 * mass * velocity^2. Plug in the mass and velocity values obtained from steps 1 and 2, respectively, and calculate the result.

Repeat these steps for each car to calculate the kinetic energy before braking.
