The temperature will increase
I think it is when shot scrapes off the top of the turf
The temperature of the lithosphere is around 300<span>°C</span> - 500<span>°<span>C</span></span>
By definition, the gain in PE (potential energy) is
ΔPE = m*g*h
Given:
mg = 40 N (Note that m*g = weight)
h = 5 m
ΔPE = (40 N)*(5 m) =200 J
Answer: 200 J
