A car travels on a circular track of radius R = 209 m, with increasing speed v = R α t. [t = time; α = 0.12083 radians per second2.]
(A) What is the angular position at t = 30 s (relative to t = 0) ? Express the answer in degrees between 0 and 360 degrees.
(B) Calculate the angular component of acceleration, aφ, at t = 30 s.
(C) Calculate the radial component of acceleration, ar, at t = 30 s.
