Answer:
Step-by-step explanation:
To find speed of ball we will use formula.
To find distance traveled by ball we will add length of ramp and distance from the end of ramp to the wall.
Now we will substitute our values in speed formula to find our answer.
Therefore, speed of ball will be 8 meters per second.
I think its A hope this helps!!!!!!!

Quesiton 7:
To find perimeter we add all the sides together.
x+2x+2x+5=145
Combine all the x's.
5x+5=145
To isolate the constants, subtract 5 from both sides.
5x=140
Now divide both sides by 5 to isolate the x.
x=28
The questions asks for the length of AC, so to find that we need to insert our new x.
AC= 2(28)+5
56+5=61
