# Spring Constant AP Physics

1. Homework Statement

This is AP Physics C 2003 M2 by the way...

2. Homework Equations

Kinematics: vf^2=vi^2+2a(d)

3. The Attempt at a Solution

a) Speed of the clay uses kinematics. Clay starts at rest, accelrates at gravity=9.8, and the distance is H:

vf^2=vi^2+2a(d)

vf^2=2(9.8)(H)

vf=$$\sqrt{}19.6H$$

b) The speed of the pan...hmmmm..so I would guess that it's the same as the speed of the clay just was, but I'm not sure if I can make that assumption.

Thanks for the help, by the way. =)
