Answer:
Step-by-step explanation:
h=-5t+ 30t +35, where h is the height in meters and t is the time in seconds.
Considering the fact that the launched Rocket will hit the ground, it implies that the height will be zero. Hence the equation will be .
0 =-5t+ 30t +35
-5t+30t = -35
25t = -35
To find t, divide both sides by 25
25t/25 = -35/25
t = - 7/5
t = -1.4secs
Hence the time for the launched rocket to hit the ground will be -1.4secs
