A) Where is the object 3 seconds after we threw it?
B) How long does it take the object to hit the ground?

Either the equation got printed wrong, or else you copied it wrong. The equation should be h= -16t-squared + 160t + 1200. The object's height after 3 seconds is the value of h when t=3. The object hits the ground when h=0.
