Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = 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. (20 pts)
