Problem 2 A sphere with mass 3 kg slides along a rod which is bent in a vertical plane into a shape that can be described by a equation y=8-0.5x where x and y are measured in meters. When x=2m the collar is moving along the rod at speed 5 m/s and the speed is increasing at a rate of 3 m/s². Determine the normal and tangential components of the force being exerted on the sphere by the rod. P = [1 + (dy/dx)2]3/2 d²y/dx² 8 m 2 m 78-122
