Jack is driving with a pail of water along a straight pathway at a steady 25 m/s when he passes Jill who is parked in her minivan waiting for him. When Jack is beside Jill, she begins accelerating at the rate of 4.0 × 10−3 m/s2 in the same direction that Jack is driving. How long does it take Jill to catch up to Jack?

1 answer

d1 = d2
25t = 0.5a*t^2
25 = 0.5a*t
0.002t = 25
t = 12,500 s. = 3.5 h.
