Malar is playing with a toy car track set and has made a vetical loop she wants to send a 150-gram car around. She has a hill for the car to roll down and if she releases it from a height of 24 cm above the top of the loop, which has a radius of 20 cm, it goes around the loop and exits with a speed of 3.12 m/s. How much energy was lost due to friction (between the car and the sides of the track, and the car's axels) during the entire trip? Hint: You don't have any details about the time while the car is going down the hill or through the loop, so you don't know how fast it is going at the top of the loop.
