Q. Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, please derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tangential acceleration taof the angular motion.
