Answer:
We could get the time taken by the ball to return back to earth, using the formula:
s = u t + ½ a t², where
s = displacement of the body moving with initial velocity u, acceleration 'a' in time t.
In the present case s=0 (as the ball returns back to starting time)
u= 30 m/s; a = -10 m/s² ( negative sign as a is in opposite direction to u); t=?
0 = 30 t - ½ ×10 ×t²; ==> 5 t = 30, t= 6 second.
So ball will return back after 6 second after being thrown up.

Answer:
The moon moves because the earth rotates around its axis of rotation. Although the moon moves too around its orbit, the speed is too small to notice. In other words, the moon's position changes insignificantly, however, the earth rotates fast enough to notice.
Answer:
The force makes it go slower or faster depending on it's mass.
Explanation:
Force = mass times acceleration
Answer:
The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.
