1. The problem statement, all variables and given/known data I'm not particularly confident with my calculations and I would appreciate any feed back. A) What is the kinetic energy of an object with: mass = 5lbm velocity = 200 ft/sec B) What is the potential energy of an object with: mass = 5lbm height = 200ft g = 32.2 ft/sec2 C) What is the pressure difference between the top and bottom of a water column that is 15ft high and gravity is 32.2 ft/sec2 2. Relevant equations KE = 1/2mv2/gc PE = mgh/gc 3. The attempt at a solution A) KE = 1/2(5 lbm)(200 ft/sec)2/32.17 ft-lbm/lbf-sec2 KE = 3.11x103 lbf-ft B) PE = (5 lbm)(32.2 ft/sec2)(200ft)/32.17 ft-lbm/lbf-sec2 PE = 1001 lbf-ft C) I'm not quite sure where to start with this one and I would appreciate an guidance.
