1. The problem statement, all variables and given/known data A particle moves in a plane with constant radial velocity (r dot) and constant angular velocity (theta dot). When the particle is at distance r from the origin, determine the magnitude of the acceleration. r dot = 4.3 m/s theta dot = 2.5 rad/s r = 3.1 m speed of the particle at r = 8.86 m/s 2. Relevant equations v = (((r dot)^2)+((r*(theta dot))^2))^.5 3. The attempt at a solution I have attempted to find the derivative of the above equation, but I am not sure if I am doing the derivate wrong.
