Write a vector expression for the ball's position as a function of time (in m), using the unit vectors î and ĵ. (give the answer in terms of t.) r = m by taking derivatives, do the following. (b) obtain the expression for the velocity vector v as a function of time (in m/s). (give the answers in terms of t.) v = m/s (c) obtain the expression for the acceleration vector a as a function of time (in m/s2). a = m/s2

What point is the projection of q on a) r b) s c) t

6x + 3y = -6 2x + y = -2 a. x = 0, y = -2 b. infinite solutions c. x = -1, y = 0 d. no solution
