You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 4.00 ss after it was thrown. What is the speed of the rock just before it reaches the water 29.0 mm below the point where the rock left your hand? Ignore air resistance.
A plane accelerates down a runway. Markers beside the runway are 9.3 m apart. The plane moves between two adjacent markers in 0.196 s. Estimate the instantaneous speed of the plane as it passes the first marker.
A hare and a tortoise compete in a race over a course 1.00 km long. The tortoise craws straight and steadily at its maximum speed of 0.200 m/s toward the finish line. The hare runs at its maximum speed 8.00 m/s toward the goal for 0.800 km and then stops to tease the the tortoise. How close to the goal can the hare let the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds.

The horse runs for 1.600 km and then stops to tease the slow-moving squirrel, which eventually passes by. The horse waits for a while after the squirrel passes and then runs toward the finish line. Both animals cross the finish line at the exact same instant. Assume both animals, when moving, move steadily at their respective speeds.
