If a ball is launched horizontally at 40 m/s from a bridge, what will be the magnitude of its velocity after 3 seconds?
30 m/s
40 m/s
50 m/s
70 m/s
What is the relationship between motion in the x and y-dimensions?
If x is greater, then y is greater
If x is greater, then y is less
There is no relationship; independent
