Ann, running with a speed of 4.00 m/s along a straight track, passes Beth who is stationary. Ann continues to run with the same speed for another 600 m. As soon as Ann passes her, Beth starts running with a constant acceleration of 0.045 m/s2.
(a) When Ann is at the 600 m mark, where is Beth?
(b) How fast is Beth running at that time?
At this time, Ann starts accelerating with a constant acceleration. She continues to accelerate for 60.0 s when she reaches a speed of 7.50 m/s.
(c) What is the magnitude of Ann’s acceleration?
(d) How long after she starts running does Beth pass Ann?
