A 11.8-kg monkey is hanging by one arm from a branch and swinging in a vertical circle. Assume a radial distance of 99.8 cm between the branch and the point where the monkey's mass is located. As the monkey swings through the lowest point on the circle, it has a speed of 3.22 m/s. Find:

a. The magnitude of the centripetal force acting on the monkey.

b. The magnitude of the tension in the monkey's arm.
