A hoist powered by a 15 kW motor is used to raise a 500 kg bucked to a height of 80 m. If the efficiency is 80% . Find the time required.

Explanation

To solve the problem of finding the time required to raise a 500 kg bucket to a height of 80 m using a 15 kW motor with an efficiency of 80%, we can follow these steps:

### Step 1: Calculate the Weight of the Bucket
The weight (force due to gravity) of the bucket can be calculated using the formula:
\[ \text{Weight} = \text{mass} \times \text{gravity} \]
Given:
