Chapter 3, Problem 24(choose chapter or problem)
Gertrude is aiming a Super Drencher water pistol at Egbert, who is 1.6 m tall and is standing 5 m away. Gertrude holds the water gun 1 m above ground at an angle of elevation. (See Figure 3.14.) (a) If the water pistol fires with an initial speed of 7 m/sec and an elevation angle of 45, does Egbert get wet?(b) If the water pistol fires with an initial speed of 8 m/sec, what possible angles of elevation will cause Egbert to get wet? (Note: You will want to use a computer algebra system or a graphics calculator for this part.)
