Because of your physics background, you have been hired as a consultant for a newmovie about Galileo. In one scene, he climbs up to the top of a tower and, in frustration over the people who ridicule his theories, throws a rock at a group of them standing on the ground. The rock leaves his hand at 30 degrees from the horizontal. The script calls forthe rock to land 15 m from the base of the tower near a group of his detractors. It isimportant for the script that the rock takes precisely 3.0 seconds to hit the ground sothat there is time for a good expressive close-up. The set coordinator is concerned thatthe rock will hit the ground with too much speed, causing cement chips from the plazato injure on of the high priced actors. You are told to calculate that speed.
Suppose a projectile is fired from a cannon with velocity vo
and angle of elevation 0. The horizontal distance R (0) it travels (in feet) is given by the following.
