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:

Question
**Physics Problem: Energy Loss in a Toy Car Track**

Malar is using a toy car track set and has constructed a vertical loop. She plans to send a 150-gram car around it. The car is released from a height of 24 cm above the loop, which has a radius of 20 cm. The car successfully navigates the loop and exits with a speed of 3.12 m/s.

**Problem:** Calculate the energy lost due to friction (between the car and the sides of the track, and the car's axles) during the entire journey.

**Hint:** You are not provided with details about the time the car spends going down the hill or through the loop. Consequently, the speed at the top of the loop is unknown.
