Homework Statement
A ball of moist clay falls 12.0 m to the ground. It is in contact with the ground for 22.0 ms before stopping.
(a) What is the average acceleration of the clay during the time it is in contact with the ground? (Treat the ball as a particle.)
Homework Equations
v^2 = u^2 + 2gh
v=final speed
u= initial speed
The Attempt at a Solution
I'mm not sure where to start this, as I don't think it is asking about the whole thing, but the 22 ms? I'm lost here.
