Homework Help: AP Physics

Posted by Soph on Sunday, September 23, 2012 at 5:54pm.

Jack is 12m from the bus and is running towards the bus at a constant 4.0m/s. If the bus accelerates away from the bus stop at .8m/s^2, can he catch the bus? If so where?

Vi= initial velocity
vf=final velocity
a= acceleration

I found out that it takes Jack 3 seconds to reach where the bus was originally at the 12m. But after that i have no clue how to finish it.
