4 UNANSWERED A 1.0 kg metal head of a geology hammer strikes a solid rock with a velocity of 5.0 m/s. Assuming all the energy is retained by the hammer head, how much will its temperature increase? (chead 5 0.11 kcal/kgC°) 4 UNANSWERED A 1.0 kg metal head of a geology hammer strikes a solid rock with a velocity of 5.0 m/s.

Explanation / Answer

apply total KE = HEat energy obsorbded

0.5 mv^2 = mcDT

as m is same , we get 0.5 v^2 = cDT

change of temperature DT = 0.5 * 5*5/(0.11)

dT = 113.63 deg
