AP EAMCET · PHYSICS · Work Power Energy
The average power generated by a 90 kg mountain climber who climbs a summit of height 600 m in 90 minutes is \(\left(\right.\) Acceleration due to gravity \(\left.=10 \mathrm{~ms}^{-2}\right)\).
- A 100 W
- B 25 W
- C 200 W
- D 50 W
Answer & Solution
Correct Answer
(A) 100 W
Step-by-step Solution
Detailed explanation
Average power, \(\mathrm{P}_{\mathrm{av}}=\frac{\mathrm{w}}{\mathrm{t}}=\frac{\mathrm{mgh}}{\mathrm{t}}=\frac{90 \times 10 \times 600}{90 \times 60}\) \(=100 \mathrm{~W}\)
