1. The problem statement, all variables and given/known data A block of material of mass m and specific heat c falls from height h and reaches speed v just before striking the ground. Its temperature is measured immediately after it strikes the ground. If we ignore any change in temperature owing to interaction with the air, the change in temperature of the block of material is a. v2/2c b. gh/c c. vgh/c d. All of the answers above are correct. e. Only (a) and (b) above are correct 2. Relevant equations mgh = deltaQ + .5mv2 Q = mcT 3. The attempt at a solution I'm confused because by my understanding, the answer should be (gh-(v2/2))/c which is a combination of both A and B. However, this does not mean that both A and B are correct as answer choice E states. I obtained this answer by simply isolating T in the aforementioned relative equation. Am I missing something?
