The height of an object tossed upward with an initial velocity of 104 feet per second is given by the formula h= -16t^2 + 104t, where h is the height in feet and t is the time in seconds. Find the time required for the object to return to its point of departure.
:
When the object hits the ground, h=0. So set the equation =0 and solve for t.

t=0, this is the time when the object was thrown.

The object will return to its point of departure at t=6.5 s.
Happy Calculating!!!
