(a) d(t) ?
(b) the time in the air ?
(c) the maximum height ?
(d) the instantaneous velocities at t= a, and t= b?
(e) the average velocity from t= a to t= b?
(f) the velocity of the stone as it runs into the ground ?
(g) the total ground distance traveled ?
+ (for initial speed = 49 m/s, a= 4 sec, b= 9 sec.)
