You need to give the timeline of the events mixed up so we can under stand your question. If you want to learn more about this go to the internet it might help you
Those conditions are met when you have an elastic collision of equal masses.
So the answer would be a tennis ball.
Let us write momentum conservation law for this problem. The left-hand side is before the collision and right-hand side is after the collision:
What this equation means is that all momentum of the first ball is transferred to the second ball and velocities before and after the collision are the same.
There is no need to write energy conservation law. We can see that above equation holds true only if
.
<span>F = GMm/r^2
but we don't want force we want acceleration.
F = ma
combining the two
ma = GMm/r^2
cancelling m from both sides
a = GM/r^2
where G is the universal gravitational constant M is the mass of Saturn and r is the radius of Saturn.
g(Saturn) = a = (6.67x10^-11m^3kg^-1s^-2)(5.68x10^26 kg)/(5.82x10^7m)^2
g = 11.18 m/s^2 round to 11.2 m/s^2</span>
Answer:the distance it travels in each second is decreasing
