A stone is dropped from the upper observation deck of a tower, 950 m above the ground. (Assume g -9.8 m/s2) (a) Find the initial values of the velocity v (in m/s) and the distances (in meters) of the stone above the ground. (0) - s(0) - Find the velocity (in m/s) of the stone at time to m/s m (t) - m/s
