hey, these problems are for my physics 201 class and i understand what's goin on somewhat i just need help in my approach to the problems. They have to do with one and two dimensional motion and vectors.

#1 A rock is dropped from rest into a well. The sound of the splash is actually heard 2.3 s after the rock is released from rest.(a) How far below the top of the well is the surface of the water? The speed of sound in air (at the ambient temperature) is 336 m/s.(b) If the travel time for the sound is neglected, what percentage error is introduced when the depth of the well is calculated?

#2 solved, thank you

any help would be GREATLY appreciated
