The rocket is on the ground when s(t) = 0, initially att= 0 seconds and then later when it returns to the ground after being launched vertically into the air. Solve s(t) = 0 for t> 0 to determine how many seconds it takes the launched rocket to return to the ground. 120Vt- 15t2 = 0 %3D 15 = 0 seconds

(b) After how many seconds does the rocket return to the ground?
The rocket is on the ground when s(t) = 0, initially at t = 0 seconds and then later when it returns to the
ground after being launched vertically into the air.
Solve s(t) =0 for t> 0 to determine how many seconds it takes the launched rocket to return to the
ground.
