Answer:
12.686cm
Step-by-step explanation:
By using pythagoras, we can find CB.
We know that
Therefore,
(it has to be positive since it is distance)
now we look at triangle BCD and use SOH CAH TOA.

The equation is:
h ( t ) = - 16 t² + 60 t + 3
The toy rocket will reach the ground when: h ( t ) = 0
- 16 t² + 60 t + 3 = 0
t 1 = - 0.05
t 2 = 3.8
Answer:
