A point on a rotating turntable 20.0 cm from the center accelerates from rest to a ﬁnal speed of 0.700m/s in 1.75s. (a) At
t = 1.25s, ﬁnd the magnitude and direction of the radial acceleration, (b) the tangential acceleration, and(c) the total acceleration of the point.
The Attempt at a Solution
I don't know how to find the total accelleration, are the components of the vector [tex]a^→=(a_c, a_t)=(1.25, 0.5)m/s^2[/tex]??
