Homework 7 Problem 2
Monday, April 11th, 2016
2a) Calculate the minimum initial speed required for him to reach the top of the building for an arbitrary takeoff angle theta.
2b) Plot the minimum initial speed (calculated in 2a) vs. the takeoff angle from 60 o -85o.
2c) Using Cotter’s method, determine whether the height of the building or the takeoff angle is more sensitive in calculating the minimum initial speed.

Should we use 300 and 400 feet as the min and max for the height in 2c? I assume 60 and 85 for the angles?
Those were the values I used, since those were the max and min values given for this problem set!
I don’t really understand what question c is asking. How can the initial speed be a function of initial speed?
The homework was revised. It’s a typo. The variables are building height and angle theta as function of the initial velocity
