A particle is traveling counterclockwise in a circle of radius

r = 2.85 m.

At some instant in time, the particle is located by the angular coordinate

α = 34.0°,

the total acceleration has a magnitude of

a = 19.0 m/s2

and is directed at an angle

β = 20.0°

with respect to the radial coordinate. Determine the following at this instant. (Express your answer in vector form.)
determine the velocity and acceleration
