Question

Q4. If the formula for work is Work = Force x Distance, how much more work would you do in lifting a 10-pound barbell 3 feet instead of 2 feet? (a) half as much (b) three times as much (c) one-third as much (d) one and a half times as much (4) marks​​​​​

Answer 1

Answer:

(d) one and a half times as much

Explanation:

W=Fd  {Work = Force x Distance}

1)  W = (10lb)(3 ft) = 30 ft-lbs work

2)  W = (10 lb)(2 ft) = 20 ft-lbs work

30/20 = 1 and 1/2 times as much
