Question 1003334: if an object is thrown downward with an initial velocity of Vo. Then the distance it travels is given by S=4.9t^2+Vot. an object thrown downward from an airplane 500m from the ground with an initial velocit of 8 m/sec. how long does it take for an object to reach the ground?

if an object is thrown downward with an initial velocity of Vo. Then the distance it travels is given by S=-4.9t^2+Vot. an object thrown downward from an airplane 500m from the ground with an initial velocity of 8 m/sec. how long does it take for an object to reach the ground?
------
S(t) = -4.9t^2 - 8t + 500
-------
Solve:: -4.9t^2 - 8t + 500 = 0
-------
t = 9.36 seconds
---------
