Question

In a physics lab a 90 kg student runs up a 1.5 meter tall flight of stairs in 3.0 seconds. The students power rating is approximately ___W

Answer 1

The power generated by the students will be .
•Work done is equal to
Mgh = 90*9.8*1.5
1587.6 j
thus power is equal to work done by time
1587.6/3
529.2 j/secs
