a student who weighs 500 newtons climbed the stairs frim the first fkoor to the third floor 15 meters above in 20 second

How much work did she do?
what was her power?
How do you write this question out HELP

To calculate the work done by the student, we can use the formula:

Work = Force × Distance × cos(θ)

where Force is the weight of the student (500 N), Distance is the height of the stairs (15 m), and θ is the angle between the applied force and the displacement (in this case, it is 0 degrees as the force and displacement are in the same direction vertically).

So, the work done by the student is:

Work = 500 N × 15 m × cos(0°)

cos(0°) = 1 (since cos(0) = 1)

Work = 500 N × 15 m × 1 = 7500 Joules

Therefore, the student did 7500 Joules of work.

To calculate the power, we can use the formula:

Power = Work / Time

where Work is the amount of work done (7500 J) and Time is the time taken to climb the stairs (20 seconds).

Power = 7500 J / 20 s = 375 Watts

Therefore, the student's power is 375 Watts.

In terms of how to write the question:

"A student who weighs 500 newtons climbed the stairs from the first floor to the third floor, which is 15 meters above. It took her 20 seconds to complete the climb. How much work did she do? What was her power?"
