Moon and Earth have different gravitational constants- g. g on the Earth is <span>equal to 9.8 m/s^2 while g on the moon is equal to 1.6m/s^2.
</span><span>Let assume that two balls are thrown: one on Earth and one on Moon and that their kinetic energy is the same.
The kinetic energy is E=(m*v^2)/2.
So, this means that t</span><span>he ball would fall much more slowly on Moon than on Earth. Every aspect of the ball's fall would be slower.

Answer:
The minimum acceleration will be
Explanation:
We have given that coefficient of static friction
Frictional force is given by
Weight is given by
For train to allow the bat to remain in place
So the minimum acceleration will be
A=vf-vi/tf-ti
a= velocity final-velocity initial / time final-time initial
a= 6 m/s - 3 m/s divided by 8 s - 0s
a= 2 m/s / 8 m/s
a= 1/4 m/s^2
