# Physics Kinematics Example

A ball is thrown downward with a speed of 15 m/s from the roof of a 30 m building. At the same instant a ball is thrown upward with a speed of 15 m/s from ground level. Relative to ground level, at what height do the two balls pass each other?

A swimmer can swim with a velocity of 1.0 m/s in still water. The swimmer wishes to swim directly across a river with a current of 0.50 m/s directed from upstream to downstream. To end up directly across the river the swimmer must head at what angle?

In a rescue attempt, a hovering helicopter drops a life preserver to a swimmer being swept downstream by a river current of a constant velocity v. The helicopter is at a height of 9.8 m. The swimmer is 6.0 m upstream from a point directly under the helicopter when the life preserver is released. It lands 2.0 m in front of the swimmer. How fast is the current flowing?
