Hi, please help! •_• One workman is measured as having a power of 528W. His weight is 800N. He can develop the same power climbing a ladder, whose rungs are 30cm apart. How many rungs can he climb in 5s?

He can climb 11 rungs

Explanation:

Power = 528W, Force = 800N, Time= 5s Total Distance moved = 30x cm or 0.3x m, where x is the number of rungs he climbed

Power = Work done/time

Work done = Power × time

= 528 × 5

= 2640Joules

Also Work done = Force × total distance moved

Total Distance moved = Work done/force

0.3x = 2640/800

0.3x = 33

x = 3.3/0.3

x = 11
