Number 4 I think
the atomic mass is 11 because the mass is the sum of protons and neutrons
I would say D would be the answer. but is this even a real like homework question
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.
Answer:
-26 m/s.
Explanation:
Hello,
In this case, since the vertical initial velocity is 26 m/s and the vertical final velocity is 0 m/s at P, we compute the time to reach P:

With which we compute the maximum height:

Therefore, the final velocity until the floor, assuming P as the starting point (Voy=0m/s), turns out:

Which is clearly negative since it the projectile is moving downwards the starting point.
