A mass m = 0.100 kg is moving along a circular track with radius R = 0.300 m. The position of m as a function of time t is given by the equations x = Roos o y = Rsin o $ = wt + at? w = 100 rad s-1 a =25.0 rad s-2 We write the acceleration of m in terms of the unit vectors of plane polar coordinates a = ari + add Calculate a, at 1 = 3.00 s. Enter the value of a, in m s-2 with 3 significant digits
