Hi! I have some questions from a study guide in my physics class, and they give me the answer, but I have to show how to get the answer. I did most of them, but need help with these. Here is problem #4:
What is the increase in thermal energy to a 2000 kg bus and its surroundings if that bus comes to a stop from a speed of 15 m/s? Ignore other sources of thermal energy. (225000 J)

Q=ΔKE=mv²/2

How did you type the exponents? And the triangle?
