Two identical balls, Ball A and Ball B are launched with the same initial velocity \(v\) along a pair of tracks. The first track with Ball A, is a straight track. The second track with Ball B, has a “U”-shaped dip in the middle so the ball goes down and then back up.
Which ball reaches the end of the track first, if friction is neglected?
It depends on the horizontal location of the U-shaped dip.It is not possible to predict this with 100% certainty.
It depends on the height of the dip.
They reach the end of the track at the same time.
Ball B will reach the end of the track first.
