1. [Total of 8 marks] A particle, initially at rest, slides down a frictionless circular path that is vertical at the top as shown in Figure 1 below. The radius of curvature remains constant along the path so that the path becomes flat at the end (point D). For positions A, B, C and D, a) Rank the magnitude of the velocity of the block (smallest first and mention any ties) b) Sketch the approximate direction of the resultant acceleration of the particle (sketch on the figure below) any ties); c) Rank the magnitude of tangential acceleration (smallest first and mention d) Rank the magnitude of normal acceleration (smallest first and mention any ties).
