Unformatted text preview: we can choose the origin of coordinates such that v r = 0 at t = 0 . Let v =u at t = 0 . Even with this restriction, we still have a freedom to choose the value of r at t = 0 . What should we choose for r at t = 0 such that we have v r = 0 initially? (c) Solve for v r ( t ) and v ( t ) with the initial conditions from part (b). Hint: You may need to use a result from differential equations about rst order equations....
