. Suppose a baseball is thrown vertically upward from the ground with an initial velocity v0. The approximate height of the ball above the ground after 1; seconds is given by 3(t) = 16t2 + out. (a) What is the height of the ball at its highest point? (b) With what velocity does the ball strike the ground? . Suppose the position of an object moving horizontally along a line after :3 seconds is given by the function 5 = f(t) = 1815 3t2, where t 6 [0,8], with s > 0 corresponding to positions right of the origin. (a) Graph the position function; (b) Find and graph the velocity function. When is the object moving to the right? (6) Determine the velocity and acceleration of the object at t = 1. (d) Determine the acceleration of the object when its velocity is zero. (e) On What intervals is the speed increasing
