A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by X = 18.0t and y = 4.00t - 4.90t2, where x and y are in meters and t is in seconds.
(a) Write a vector expression for the ball's position as a function of time, using the unit vectors i and j.
(B) taking derivaties, obtain expressions for (b) the velocity in vector v' as a function of time and
(c) the acceleration vector a as a function of time.
(d) Next use unit-vector notation to write expressions for the position, the velocity, and the acceleration of the golf ball at t = 3.00s.
