answer me please

Find Position, velocity and Acceleration vectors The motion of a point on the circumference of a rolling wheel of radius 3 feet is described by the vector function T(t) = 3(21t - sin(21t)) i + 3(1 - cos(21t)) j Find the velocity vector of the point. v (t ) = Find the acceleration vector of the point. a(t) = Find the speed of the point. s (t) =
