A 12.0 m long conveyor belt, inclined at 30.0°, is used to transport bundles of newspapers from the mailroom up to the cargo bay to be loaded on to delivery trucks. Each newspaper has a mass of 1.0 kg, and there are 25 newspapers per bundle. Determine the power that the conveyor develops if it delivers 15 bundles per minute.

Power = 367.5 Watts

Step-by-step explanation:

Given:

Length of conveyor belt = 12.0 m

Conveyor inclination = 30.0°

Mass of each news paper = 1.0 kg

Each bundles = 25 news paper

Solution:

Mass of each bundle to transport m

Inclination of the conveyor belt h = (Length of the conveyor belt) (Sin(30.0°))

Using power formula.

Substitute all values in above equation.

Power = 367.5 Watts

Therefore, Conveyor must have 367.5 Watts to delivers 15 bundle per minute.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
