In lab we determined the specific heat of several cubes of metal. One of those cubes was lead which had a specific heat of 0.13 J/g oC. Let’s imagine a thought experiment where we drop a 100 g piece of lead off the roof of a 10 meter tall building. A. How much will the temperature rise for the lead when it hits the ground? B. How much potential energy does the lead have at the top of the roof? C. How much kinetic energy does the lead have just prior to striking the ground? Assume that the mechanical energy is conserved and transferred to the lead to be thought of as heat, Q. Using Q = mc(T-To), solve for (T-To), the change in temperature.

Problem 3 An asteroid closely passes the Earth at a range of 17200 mi and relative speed of 7.8 km/s. The diameter is estimated at 30 m with a specific gravity of 3. If this asteroid had impacted Earth, how much energy would have been released? Express this quantity in units of mega- tons (Mton) where a megaton is the energy released by one million metric tons of TNT explosive. A metric ton is 1000 kg and the explosive energy density of TNT Hint: If the asteroid hits the Earth, its relative velocity becomes zero. Ignore any change in asteroid velocity due to gravitational acceleration or air resistance. 4184 J/g.
Bob heats up a bottle of milk for his baby, Jill, every morning. Jill will only drink the bottle if it is at 98 degrees. So Bob places the bottle in a cup of hot water (170 degrees). The bottle starts off at 35 degrees. Use Newton's heating-cooling law, that the rate of change in the temperature, H, is proportional to the difference between the object and the surrounding temperature. Explain why you can't solve this problem if all you know is the initial temperature of the milk and the final required temperature of the milk.
