Help......A 1.0kg metal head of a geology hammer stikes a solid rock withy a velocity of 5.0m/s. Assuming all the energy is retained by the hammer head, how much will its temperature increase? (C
head= 0.11kcal/kgCdegrees) I don't comprehend any of this!

• Pys. Science -

kinetic energy in hammer= heat in hammer
1/2 m v^2= m*specificheatSteel*deltatemp

change in temperature= (1/2mv^2)/(m*specifheat)

change in temperature= v^2/(2*specificheat)

• Pys. Science -

change in temperature: (5m/s)^2 /2*920

Did you change kcal to joules? .11kcal=920Joules check that.
