A force of 100 newtons was necessary to lift a rock. A total of 150 joules of work was done. How far was the rock lifted?
|
|
1.5m
|
|
|
15, 000 m
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -W = 150 J and F = 100N. Joules can be converted into Newton ⋅ meters, so the entire equation can be written as 150 N ⋅ m = 100N ⋅d . Dividing by 100N on both sides results in the expression 1.5m = d . Thus, d, or distance equals 1.5 meters.
Detailed explanation-2: -Solving this we, the work done, is equal to 360 newton meter or 360 joules hope you find this video interesting.
