A line OP of ﬁxed length L rotates in a plane about the ﬁxed point O. At time t = 0, the line is at the
position OA. At time t, angle AOP = θ radians and dθ/dt= sin θ. Show that, for all t, the magnitude of
the acceleration of P is equal to the magnitude of its velocity.
hey guys could you please explain the concept behind this question and the solution too. Greatly appreciate it.
Thanks
