A particle moves in an xy plane in such a way that its distance r from the origin depends upon time t as r 3t The angle 9 made by its position vector with the positive x axis at any time t is given as 9 2t Here r is in metre 0 in rad and t in second y 0 V R P The particle moves in Straight line At time t 0 5 s its speed is 2 m s At time 0 5 s its velocity vector makes an angle 45 with its position vector at the same time At time t 0 5 s its velocity vector makes an angle 30 with its position vector at the same time
