Question
A particle moves in the x- y plane with velocity v= = (1-r)î+(4– 2r + 1*)j where t is the time and i and j are unit vectors in the x and y coordinate directions respectively. (а) Calculate the initial speed of the particle. The particle is initially at a point with position vector c= 31 - j. Find its position at time t = 3. Obtain the acceleration of the particle (as a function of time). (b) (c) (d) At what time is the acceleration of the particle perpendicular to PQ where P and Q are points with coordinates (-5,0) and (1,2) respectively?
