A lead bullet with a mass of 8.50 g traveling at 4.80 x 102 m/s strikes a 2.00 kg block of wood and is embedded in it. Both the bullet and the block are initially at 25.0°C. Assume that no heat is lost to the surroundings and that all the kinetic energy of the bullet is converted into heat in the block. The specific heat capacity of wood is

2.1 J/g • K and the specific heat capacity of water is 4.18 J/g • K.

A. What is the kinetic energy of the bullet? (4 points)

B. How much energy does the block absorb? (2 points)

C. What is the final temperature of the block? (4 points)

D. If the bullet was shot into 2.00 kg of water at 25.0°C, rather than into the block of wood, would the final temperature of the water be greater or less than 25.2°C? (2 points)

Sorry, those are the questions...
