π 4 Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = 1 rad, the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is € = 2 rad/sec². What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle by observing a right triangle. 0 2 m Figure 3: Particle pushed by rod along vertical path.
