When an object is dropped, the distance it falls in t seconds. assuming that air resistance is negligible, is given by s(t) = 4.90m2 where sit) is in meters (m) if a stone is dropped from a cliff, assuming that air resistance is negligible, nd the velocity and acceleration of the stone after it had been falling for 6 sec. E m The velocity of the stone is D sec ' (Type an integer or decimal rounded to two decimal places as needed.)
