In 1939, joe sprinz of the san francisco baseball club attempted to break the record for catching a baseball dropped from the greatest height. members of the cleveland indians had set the record the preceding year when they caught baseballs dropped about 210 m from atop a building. sprinz used a blimp at 240 m. neglect the effects of air on the ball and assume that the ball free falls that distance. key idea assuming that we can neglect the effects of the air, once the ball leaves the blimp and before it is caught, its acceleration is the free-fall acceleration ag. because this acceleration is constant, the constant-acceleration equations apply to the motion. here we will use the symbol y instead ofx, and in the calculations we will substitute-g for a. in terms of the ball's displacement y - yo and its acceleration -g, and setting the initial velocity vo to 0 (the ball is released, not thrown upward or downward), what is the ball's time of fall?

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)
