A person was shot vertically upward from a cannon with a mass 52 kg and a speed of 35 m/s. a) what was the height according to conservation of energy and b) what was the person's total energy? (TME never changes!)
a) used TMEo=TMEf
height= 63 m.
b.)Would I use PE=mgh

I get 62.5 using g=9.8
Agreed.
a) h = 62.5 m
= 6.3 x 10^1 m
b) PE = mgh
=(52)(9.8)(62.5)
= 31850 j
= 3.2 x 10^4 J
