Problem
A 5.00 g lead bullet moving at 44.0 m/s penetrates a wood block and comes to rest inside the block. If half of its kinetic energy is absorbed by the bullet, what is the change in the temperature of the bullet? The specific heat of lead is 128 J/kg⋅K.
(a) 0.940 K
(b) 1.10 K
(c) 1.26 K
(d) 3.78 K
