A point on a rotating turntable 21.5 cm from the center accelerates from rest to a final speed of 0.800 m/s in 1.75 s. At t = 1.28 s, find the magnitude and direction of each of the following.

2. Relevant equations

(a) the radial acceleration

(b) the tangential acceleration

(c) the total acceleration of the point

? m/s^2, ? °

3. The attempt at a solution

for this i used the right equations for the give times and substituded V= 2pir/T but i didnt get the right answer. i used a_r= -v^2/r and a_t= d|v|/dt....can somebody explain it in a simple way...
