A point moves in the plane so that its tangential acceleration `w_tau=a`, and its normal acceleration `w_n=bt^4`, where a and b are positive constants, and t is time. At the moment `t=0` the point was at rest. Find how the curvature radius R of the point's trajectory and the total acceleration w depend on the distance covered s.
