Answer:
x = 9.5 m
Step-by-step explanation:
Given:
This problem is based on 2D motion kinematics equations:



At maximum height:

Components of initial velocity:


To find time to reach maximum height:
Plugging in the known values:
0 = 4.10 - 9.8t


Total time = 2t = 2(0.418) = 0.836 s
to find horizontal distance covered:

Step-by-step explanation:
C and D are the correct objectives
I think that the correct answer would be 6.
I hope that this helps you !
