A car accelerates from rest to a speed of 12 m/s. The mass of the car is 1000 kg. What is the work done on the car?
To solve this problem, we can use the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy.
Calculate the initial kinetic energy
The car starts from rest, so its initial velocity . The mass of the car is , and its final velocity is .
The initial kinetic energy () is:
