point(s) possible Submit quiz When an object is dropped, the distance it falls in t seconds, assuming that air resistance is negligible, is given by s(t) = 4.90512 where s(t) is in meters (m). If a stone is dropped from a cliff, assuming that air resistance is negligible, find the velocity and acceleration of the stone after it had bee falling for 15 sec. m The velocity of the stone is sec (Type an integer or decimal rounded to two decimal places as needed.) m The stone's acceleration is sec (Type an integer or decimal rounded to two decimal places as needed.)
