Problem 2: A fisherman has caught a fish on his pole, and to keep the pole steady he has to apply an upward force of F2 = 255 N at an angle of 51.5° with respect to the pole (see figure). The length of his pole is 3.1 m, and he is holding it a distance 0.45 m from the end, where he is applying a downward force F1. Randomized Variables
F2 = 255 Nθ = 51.5°L = 3.1 md = 0.45 m

Scientists have developed a clever way to measure a mass of virus using a spring. A cantilever beam in the scanning electron microscope image below is like a diving board, except that it is extremely small (a couple of micrometer). The cantilever beam with mass m can oscillate (imagine a vibrating diving board) and it can be modeled as a spring with a spring constant k. What you can measure experimentally is the frequency of oscillation of the cantilever first without the virus (f1) and after the virus had attached itself to the cantilever (f2). (a) Find the mass of virus from f1 and f2 (assume that we don’t know the spring constant k) (b) Suppose the mass of cantilever is 10.0 * 10^-16 g and a frequency of 2.00 * 10^15 Hz without the virus and 2.87 * 10^14 Hz with the virus. What is the mass of the virus?

At the moment (let this be t = 0) when the mass is at position x = d/2 (and moving to the right), it collides and sticks to another mass m0 = m.
