Question

1.40. A particle moves along an arc of a circle of radius R according
to the law 1 = a sin cot, where 1 is the displacement from the initial
position measured along the arc, and a and co are constants. Assuming
R = 1.00 m, a = 0.80 m, and co = 2.00 rad/s, find:
(a) the magnitude of the total acceleration of the particle at the
points 1 = 0 and 1 = ±a;
(b) the minimum value of the total acceleration wmin and the corresponding
displacement lm.
