Chapter 3, Problem 6SP
An archeologist is running at 8 m/s with her hands outstretched above her head (1.85 m from feet to fingertips) while being chased by a tiger. She runs exactly horizontally off the edge of a chasm and attempts to grab onto the opposite side.
- a. If the chasm is 5.0 meters wide, how long does she take to cover this distance?
- b. During this time, what distance has she fallen vertically (use g = 10 m/s2)?
- c. How far above or below the edge of the opposite side do her fingertips fall? (Use + to indicate distances above the edge, and − to indicate distances below the edge.)

The golfer can complete the hole by hitting the ball from the flat section it lays on, up a 45∘45∘ ramp, over a moat, and into the hole which is ?=1.90 md=1.90 m away from the end of the ramp. If the opening of the hole and the end of the ramp are at the same height, ?=0.880 m,y=0.880 m, at what speed must the golfer hit the ball to launch the ball over the moat so that it lands directly in the hole? Assume a frictionless surface, so the ball slides without rotating.
