A particle moves in a circle of radius 1.0 cm at a speed given by v=2.0 t where v is in cm s-1 and t in seconds.

(a) If the radial acceleration in cm s-2 of the particle at t=1 s is α.

(b) If the tangential acceleration in cm s-2 at t=1 s is γ.

(c) If the magnitude of the accelerationin cm s-2  at t=1 s is β .

Then find α+β+γ.
