the block final comes to rest.
a) If the block absorbs 80% if its initial kinetic energy as internal energy, calculate its increase in temperature.
b) What happens to the remaining energy?

b) What happens to the remaining energy?
-
a)
dT = H/(M*C) where C is the specific heat of copper in J/(kg°C)
dT = .80*½*1.5*3.0²/(1.5*C) = 360/C C°
b)
Remaining energy heats the surface and surrounding air.
