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
