A man whose mass is 80kg climbs a staircase in 20 seconds a expends a power of 120 Watt. Find the height of the staircase
Added by Cassandra J.
Step 1
In this case, the man is doing work against gravity to climb the stairs. The formula for power is P = W/t, where P is power, W is work done and t is time. We can rearrange this formula to find the work done: W = P * t. Substituting the given values, we get W Show more…

A man weighing $60 \mathrm{~kg}$ climbs a staircase carrying a 20 kg load on his hand. The staircase has 20 steps and eacl step has a height of $20 \mathrm{~cm}$. If he takes 20 second to climb his power is: (a) $160 \mathrm{~W}$ (b) $230 \mathrm{~W}$ (c) $320 \mathrm{~W}$ (d) $80 \mathrm{~W}$
The man having the weight of 150 lb is able to run up a 15 -ft-high flight of stairs in 4 s. Determine the power generated. How long would a 100 -W light bulb have to burn to expend the same amount of energy? Conclusion: Please turn off the lights when they are not in use!
