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 lbmft/lbfsec2) = 4.53 x 1010 ftlbf
Incorrect
Ek = mv2/2gc = 4000 lbmÞ (27,000 ft./sec) /(2) (32.2 lbmft/lbfsec2) = 4.53 x 1010 ftlbf

Question 9 of 10
9. Question
What is the weight in lbf of a 1.00 lbm object in a 27.5 ft/sec gravitational field?
Correct
F = ma/gc = 1:00 lbm x 27:5 ft sec²/32.2 lbmft lbfsec² = 0.854 lbf
Incorrect
