If the coefficient of static friction between the 50-lb roller and the ground is ms = 0.25, determine the maximum force P that can be applied to the handle, so that roller rolls on the ground without slipping. Also, find the angular acceleration of the roller. Assume the roller to be a uniform cylinder.

1. The nth Fibonacci number is defined by the following recursive equations: f(1) = 1 f(2) = 2 f(n) = f(n-1) + f(n-2) Therefore, f(3)=f(2)+f(1)=2+1=3, and so forth for higher numbers. Write a function file to calculate and write out the nth Fibonacci number for n>2; n is input to the function file. Use a while loop to perform the calculation. function [f]=fibonacci(n) i=1; while i<=n if i==1 f(i)=1; elseif i==2; f(i)=2; else f(i)=f(i-1)+f(i-2); end i=i+1; end 1 point for comments 1 point for function file header 1 point for initializing I outside while loop 2 points for correct while condition 1 point for considering i==1 and i==2 (may not necessarily be inside loop) 1 point for f(i
