A 9.95 kg monkey is hanging by one arm from a branch and swinging on a vertical circle. As an approximation, assume that the radial distance between the branch and the point where the monkey's mass is located to be 84.1 cm. As it swings through the lowest point on the circle, the monkey has a speed of 2.59 m/s. Calculate the magnitude of the centripetal force acting on the monkey.
At a certain point, A, in its motion, its velocity angle is 19° above the horizontal. At another point, B, later in its motion, its velocity angle is 39° below the horizontal. Illustrate what is the horizontal distance from point A to point B?
A pair of hedge trimmers are 45 cm long from the pivot to the end of the handles. how much force is applied to the branch
Obtain an expression for the velocity
