The small ball shown in the figure is bounded to move in the vertical slot due to the rotation of the arm and has a mass of 1.5 kg. Evaluate the reaction of the slot on the ball when q = 300. The constant angular velocity of the rod is 4 rad/s. The ball contacts only one side at any instant.
a. 32.1 N in the positive
N = (F + m aq)
- m ar
The reaction of the slot on the ball is 32.1 N in the negative x-direction.
