Explanation:
no te tengo porque darte explicaciones
Answer:
final velocity will be44.72m/s
Explanation:
HEIGHT=h=100m
vi=0m/s
vf=?
g=10m/s²
by using third equation of motion for bodies under gravity
2gh=(vf)²-(vi)²
evaluating the formula
2(10m/s²)(100m)=vf²-(0m/s)²
2000m²/s²=vf²
√2000m²/s²=√vf²
44.72m/s=vf
200 N, that is if the force is balanced and the wall doesn't move
Explanation:
the correct answer is Option 5.√½gh.
hope this helps you.
