Question 7 of 10
7. Question
What is the kinetic energy in ft/lbf if a rocket with a mass of 4,000 lbm travels at 27,000 ft/sec?
Correct
Ek = mv2/2gc = 4000 lbmÞ (27,000 ft./sec) /(2) (32.2 lbm-ft/lbf-sec2) = 4.53 x 1010 ft-lbf
Incorrect
Ek = mv2/2gc = 4000 lbmÞ (27,000 ft./sec) /(2) (32.2 lbm-ft/lbf-sec2) = 4.53 x 1010 ft-lbf
