ASVAB Mechanical Comprehension Practice Test 150206

Question 1 of 5
Work

Work is accomplished when force is applied to an object: W = Fd where F is force in newtons (N) and d is distance in meters (m). Thus, the more force that must be applied to move an object, the more work is done and the farther an object is moved by exerting force, the more work is done.

If you lift a 43 lbs. rock 48 ft. from the ground, how much work have you done?

2064 ft⋅lb
