How does the initial vertical velocity, Viy, compare to the final vertical velocity, Vfy, when a ball is thrown up into the air and caught at the same height ?
Vi y and Vfy are exactly the same, this is because of symmetry
Viy and Vfiy are close but Vfy is larger because you would fall faster than you would rise, since you are slowing down
Viy and Vfy are the same in magnitude, but different in direction.
Viy and Vfy are different in magnitude and direction.

0 m/s
A ball is thrown upwards and caught when it comes back down at the same height. In the absence of air resistance, the speed of the ball when caught would be
less than the speed it had when thrown upwards.
more than the speed it had when thrown upwards.
the same as the speed it had when thrown upwards.
need more information to determine.
