To solve the problem, we need to calculate the minimum power delivered by the motor to the elevator. Here are the steps to find the solution: ### Step 1: Calculate the weight of the elevator and passengers The total mass of the elevator and passengers is given as 1500 kg. The weight (W) can be calculated using the formula: \[ W = m \cdot g \] Where: ...
