Image from http://wps.prenhall.com/esm_hibbeler_engmech_10/14/3723/953188.cw/index.html Joey steps on the track and stands still for 1 minute. Where is Joey on the platform after 1 minute? At this instant Amy steps on the track and starts to run at 2 feet per second.You are standing off to the side so to you it looks like Joey is moving at 10 feet per second and Amy is moving at the rate of 12 feet per second. From Amy's point of view Joey is standing still and she is moving at the rate of 2 feet per second. How long will it take Amy to catch up to Joey? Penny
