Answer :
Final answer:
The power required by an elevator in the given scenario involves calculating the work done over time, using the weight of the load, the height to which it is lifted, the speed of ascent, and the acceleration due to gravity.
Explanation:
The student is asking about the power required by an elevator to lift a load. Power in a physics context is the rate at which work is done or energy is transferred. In the scenario given, the elevator is lifting a load of 1160 kg to a height of 382.2 meters at a speed of 16.83 m/s. The power P required can be calculated using the formula P = (F * h) / t, where F is the force exerted by the elevator (which equals the weight of the load, F = m * g), h is the height the load is lifted, and t is the time taken, which can be found using t = h / v, with v being the velocity of ascent.
Considering the information from the reference examples, the calculation would involve the gravitational force (using g = 9.81 m/s²) and the distance covered by the elevator. However, since the time is not explicitly given in this case, it would need to be calculated by dividing the height by the elevator's speed. Once the time is found, the power can be calculated using the force and the time.
