The universal gravity formula is <span>F = G(Me)(Mm)/r^2. Lets use this formula to help us calculate what would happen if the Moon was twice as big.
</span><span>Mn = new mass = 2*Mm
</span><span>Fn = G(Me)(Mn)/r^2
</span><span>Fn = G(Me)(2Mm)/r^2
</span>Fn = 2*G(Me)(Mm)/r^2
<span>Fn = 2*F
</span>So 2 times the force it was before. The force should be the same, but you never know the moon and space as well know it can work in very mysterious ways.
4. No motion
5. Threre will be movement in one direction or another

Answer:
Explanation:
I assume you are asking for the acceleration of the ball, not the velocity (in fact, the velocity is already given).
The acceleration is:
where in this case we have:
v = 24 m/s is the final velocity
u = 0 is the initial velocity
t = 8 s is the time interval for the velocity to change
Solving the equation,
