A 9.5 kg monkey is hanging by one arm from a branch and is swinging on a vertical circle. As an approximation, assume a radial distance of 90 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 3.4 m/s.

(a) Find the magnitude of the centripetal force acting on the monkey.

(b) Find the magnitude of the tension in the monkey's arm.
