Final answer:
The work done to stop a car can be calculated using the work-energy theorem, which states that the work done is equal to the change in kinetic energy. In this case, the initial kinetic energy of the car is equal to the work done to stop it.
Step-by-step explanation:
To calculate the amount of work done to stop a car, we can use the work-energy theorem. The work done is equal to the change in kinetic energy. First, let's convert the car's speed from km/h to m/s. We can use the equation KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the car, and v is its final velocity. In this case, the final velocity is 0 m/s since the car comes to a stop. So, the work done to stop the car is equal to the initial kinetic energy, which is (1/2)(950 kg)(95 km/h)^2.
