Solution:
Here, the mass of Sparsha (m) = 40 kg
Weight of Sparsha (w) = mg = 40 × 9.8 = 392 N
Total height (h) = 15 cm × 14 = 210cm = 2.1 m
Total time taken to completely climb the ladder (t) = 10 sec
Now, using the formula of work done, we get,
w = f × d = 392 × 2.1 = 832.2 J
Again, using the formula of power, we get,
\(Power(P)=\frac{work\;done\;(W)}{time\;taken(t)}\)
= \(\frac{832.2}{10}\)
= 83.22 watt
Hence the power of Sparsha is 83.22 Watts
