Homework Statement
Jane is riding her new bike at a constant velocity of 3 m/s when she goes past Tom. Tom notices that the road will come to an end with a 30m drop. Tom grabs his bike and attempt to catch up to Jane. Jane has a 20 sec head start. Tom is going to ride at a constant...
Jane is going 3 m/s in a bike
at the end of the road is a 30 m drop.
jane passes jim
jim goes after jane 20 sec later, going 0.5 m/s^2 for 20 sec, then at a constant velocity until he reaches jane,
after jim has been traveling 8 sec, jane accelerates to 5/12 m/s^2 for 12 sec then...
