Suppose we replace the gliders with two different ones. Glider AA now has a mass of 0.20 kgkg and glider BB has a mass of 0.35 kgkg . Both still have an initial speed of 2.0 m/sm/s toward each other before the collision. Find the final velocity of Glider AA if the collision is elastic. Express your answer in meters per second.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
