Physics-half way fin.

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

  2. 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
