how much work is accomplished in lifting 60 lbs. to a vertical height of 20 ft. ?
____ ft. lbs.
○ 3
○ 120
○ 1200

Explanation:

Step1: Recall Work Formula

Work \( W \) in lifting is \( W = F \times d \), where \( F \) is force (weight) and \( d \) is distance (height).

Step2: Substitute Values

Here, \( F = 60 \) lbs, \( d = 20 \) ft. So \( W = 60 \times 20 \).

Step3: Calculate Result

\( 60 \times 20 = 1200 \).

Answer:

1200
