Answer 2

To determine the values of A (work) and N (power), we need to use the formulas related to work and power.

The formula for work (A) is given by:

A = m * g * h

where: m = mass (in kilograms) g = acceleration due to gravity (approximately 9.8 m/s^2) h = height (in meters)

Substituting the given values: m = 60 kg g = 9.8 m/s^2 h = 300 m

A = 60 kg * 9.8 m/s^2 * 300 m A = 176,400 joules

Therefore, the work (A) is 176,400 joules.

The formula for power (N) is given by:

N = A / t

where: A = work (in joules) t = time (in seconds)

Substituting the given values: A = 176,400 joules t = 1 hour = 3600 seconds

N = 176,400 joules / 3600 seconds N ≈ 49 watts

Therefore, the power (N) is approximately 49 watts.
