Q127 / 160 · AP EAMCET 2024 (22 May Shift 1) · Physics

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 $\left.=10 \mathrm{~ms}^{-2}\right)$.

  • Correct answer
    A
    100 W
  • B
    25 W
  • C
    200 W
  • D
    50 W

Solution

Average power, $\mathrm{P}_{\mathrm{av}}=\frac{\mathrm{w}}{\mathrm{t}}=\frac{\mathrm{mgh}}{\mathrm{t}}=\frac{90 \times 10 \times 600}{90 \times 60}$ $=100 \mathrm{~W}$

Hence, the correct answer is option: 'A'.
