Transcribed Image Text:

A material point moves on a curvilinear orbit with a radius of curvature of 100 m and a length of 200 m, with a decreasing speed of 0.8 m/s per second. The starting and ending points of this trajectory are defined by X and Y. If the material point has a speed of 20 m/s while passing through point Y; a) Speed at point X, b) Normal acceleration component at point Y, c) Find the resultant acceleration at point Y.
