Two Dimensional Motion Supplementary Problems 1. An object has a time dependent position vector given by rift) = {0.5 t3 i + t2 i) rn. 3) Draw a graph of the trajectory of the object for 0 s t 5 3 seconds and indicate on the graph the direction of motion of the object. b) Determine the speed of the object att = 1 s. {2.5 mfg} 6) Determine the magnitude of the acceleration of the object at t = 2 s. 2. An object moves in a circle of radius 3 m at a constant speed. completing 3 revolutions every minute. , At t : D, it is at point P and is moving counter-clockwise. 3) Find its penedz'1 T in seconds. b) Find its angular25 speed in rams. c] Find its linearze' speed. d) Find the magnitude of its acceleration-2"
