Suppose a whale is stranded on a beach. It is 15 meters from the sea. He weighs 1.5 x 10 to the power of 6, and the force a few people need to overcome to push him into the water is 0.25 times the whale's weight. How much work must the people do to push him into the water?
help me cuhh
To calculate the work done to push the whale into the water, we need to use the formula:
Work = Force * Distance
In this case, the force required to push the whale into the water is given as 0.25 times the whale's weight. Therefore, the force (F) equals:
F = 0.25 * (1.5 * 10^6)
F = 0.25 * 1.5 * 10^6
F = 375,000 N
The distance (d) over which the force is applied is given as 15 meters.
Using the formula above, the work (W) can now be calculated:
W = F * d
W = 375,000 * 15
W = 5,625,000 joules
Therefore, the people must do 5,625,000 joules of work to push the whale into the water.
