Transient Problem requiring the Excel Method

You are asked to create an Excel Spreadsheet to solve the following problem. You can look up the formula you will need to enter in your spreadsheet in the Solutions document. However I will give extra credit if you use simpler trigonometry functions. (two are all that's needed.) I will also give extra credit if you use Matlab to resolve the solution. Here is the problem.

A floor trolley has started to pull a rope to the right along the floor at 1 ft/sec. It started at time = 0 and has accelerated to its maximum speed by 1 second. It has travelled 1 foot to the position shown below. It has now drawn all the slack out of the rope and it is ready to pick up a load. It will continue at constant speed (no acceleration) as shown.

It must lift Load "A" up 3 feet so it can be loaded into a pickup truck.

Set up a spreadsheet like the ones in Blackboard under Course Documents titled "Excel Method". How long does the trolley track need to be and how long will it take from t=0 until the load is lifted 3 feet? Pick a time step that fills one page and plot Velocity of "A" versus time and rate that rope from "B to C" lengthens versus timeon a separate page.
