You said that she's losing 1.9 m/s of her speed every second.
So it'll take
(6 m/s) / (1.9 m/s²) = 3.158 seconds (rounded)
to lose all of her initial speed, and stop.
Forces are exerted I believe : all of the above
The action force might be Tyler throwing the ball
I don't know the last one
The answer would most likely be A since obviously gravity weighs things down which helps the every other masses stay settled in place
They have the same Number of protons
