1. sketch position-versus-time graphs (x versus i or/versus t) for the following motions.
include appropriate numerical scales along both axes. a small amount of computation
may be necessary.

a. a parachutist opens her parachute at an altitude of 1500 m. she then descends slowly to earth at a steady speed of5 m/s. start your graph as her parachute opens.

b. trucker bob starts the day 120 miles west of denver. he drives east for 3 hours at a
steady 60 miles/hour before stopping for his coffee break. let denver be located at x = 0
mi and assume that the x-axis points to the east.

c) quarterback bill throws the ball to the right at a speed of 15 m/s. it is intercepted 45 m
vay by carlos, who is running to the left at7.5 mls. carlos carries the ball 60 m to
ore. let. r = 0 m be the point where bill throws the ball. draw the graph for the football.
