A 100. gram steel bullet moves at 250. m/s just before imbedding itself into a thick anchored wood post. If 40.% of the initial kinetic energy goes into heating the bullet (steel c = 460.J/kg-C):
(a) how hot does the bullet become if it initially is at 25.°C? (b) what would be the bullet's temperature if it had been twice as massive ( 2 times 100. grams)?
When a spray can is being used, it feels cooler than when it was first picked up. Why?
