A lump of lead with mass 0.50 kg is dropped
from a height of 20 m onto a hard surface. It
does not rebound but remains there at rest for
a long period of time.
What are:
a) ∆Q,(b) ∆Wand (c) ∆Ufor the lead during
this process?
d) What is the temperature change in the lead
immediately after the impact? [specific
heat capacity of lead = 128 kJ/kg K]
