Unformatted text preview: s 1 from the initiation with velocity v . How far does the mass travel before it stops? 2. Look at Problem 3/97 in the book (also look at problem 2/146 that we did in class). a. Write the equation of motion for the particle in polar coordinates r,θ . b. Solve Problem 3/97. We include a friction force f f between the vane and the particle such that ¯ f f =α ˙ r ¯ e r , where α ≥ is a known constant. c. Write the equation of motion for the particle in polar coordinates r,θ while r ≤ r ≤ R . d. Find the position r ( t ) as a function of the given parameters. e. Find the force ¯ F v exerted exerted by the vane on the particle as a function of time while r ≤ r ≤ R (you can write this as a function of r ( t ) and t ).
