A quarter-circular tube AB of mean radius r contains a smooth chain that has a mass per unit length of m0. If the chain is released from rest from the position shown, determine its speed when it emerges completely from the tube

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...
