Derive time equation but for that first we have to derive acceleration using the following equations: [1] mg*sin(θ) – fs = ma [2] Rfs = Iα [3] I = cmR2 [4] α = a/R Once we have derived acceleration in terms of sin(θ), g, and c , we are then asked to derive time based on kinematic equation. The time equation should be based on of y, c, g, and d. d=length of Ramp.y=Height of ramp.

1) Up until now we have always ignored air resistance. We should now add it. Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but 2 with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bv. The coefficient bis a constant. (For this problem you can use calculus textbooks or wolfram alpha to do the calculus.) What are...
