Explanation:
2) C would need the least effort, because the longer the effort distance, the least the effort applied.
Answer:
Average force on the football = 168.82 N
Explanation:
Force = Mass x Acceleration
F = ma
Mass, m = 0.41 kg
We have equation of motion, v = u + at
Initial velocity, u = 0 m/s
Final velocity, v = 21 m/s
Time, t = 0.051 s
Substituting
21 = 0 + a x 0.051
a = 411.76 m/s²
Substituting in force equation,
F = ma = 0.41 x 411.76 = 168.82 N
Average force on the football = 168.82 N
Answer:
I did this essay before, its not hard. Just read through it carefully and you'll figure it out. or just ask you mom, dad, guardian, or teacher for help
Oh gosh oh I see it in my life face and
True. For example the Big Bang theory; no one knows what really happened, but based on evidences that were found, it was found as a good way to explain the world's origin.
