A11.6-kg monkey is hanging by one arm from a branch and swinging on a vertical circle. as an approximation, assume a radial distance of 65.3 cm is 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 3.50 m/s. find (a) the magnitude of the centripetal force acting on the monkey and (b) the magnitude of the tension in the monkey's arm.

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
