Two people stand at the same elevation on opposite sides of a narrow canyon. They each release a basketball at the same instant: the ball on the right (ball R) is dropped, the other (ball L) is thrown horizontally at 20 m/s. The two balls are exactly 100-m apart at the instant both are released. The thrown ball's path, if there was no acceleration due to gravity, is shown at 1-second intervals as a series of dots along a horizontal line. A scale is shown on the left: 1cm = 5 meters.
1. Draw the trajectory of both balls (ball L carefully, with a smooth curve & positions shown at 1-s intervals), until (a) the balls hit each other, (b) the 1st ball hits the canyon floor or (c) some other scenario. Circle the scenario chosen.
