Part (a) What is the value of the vertical component of acceleration of the free fall motion in meters per second squared? Part (b) Enter an expression for the vertical component of the total displacement of the motion, Ay, in terms of initial height h. Part (c) Enter an expression for Ay in terms of At, a, and the vertical component of the initial velocity of the motion, v;. Part (d) If the ball starts from rest, what is v;, in meters per second? Part (e) Enter an expression for At in terms of a and Ay, in the case when the ball starts from rest. - Part (f) Calculate the fall time At, in seconds, when the ball starts from rest. o Part (g) Returning now to the general case, v; # 0, enter an expression for the vertical component of the final velocity, vf, right before the ba a terms of v;, a, and At.
