You go rock climbing with a pack that weighs 50N and you reach a height of 30m. How much work did you do to lift your pack?
A. 80 joules
B. 1500 joules
C. 20 joules
D. 1.67 joules
To calculate the work done to lift the pack, we can use the formula:
Work = force × distance
In this case, the force is equal to the weight of the pack, which is given as 50N. The distance is the height climbed, which is given as 30m.
Substituting these values into the formula, we get:
Work = 50N × 30m
Work = 1500 joules
Therefore, the correct answer is:
B. 1500 joules
To determine how much work you did to lift your pack, we can use the formula: Work = force × distance.
In this case, the force is the weight of the pack, which is 50N, and the distance is the height you hiked, which is 30m.
So, to find the work done, we can substitute these values into the formula: Work = 50N × 30m = 1500 joules.
Therefore, the correct answer is B. 1500 joules.
