how do you find negative acceleration required to stop an object?
If a puck falls to a full stop in a time of 1.08 s from initial impact, what acceleration (assumed constant) is experienced by the puck during the impact with the ground?
I know the downward acceleration is constant 9.8m/s^2.. but not how to account find the velocity required to stop something
All I'm given is the time between impact and stopping (1.08s) and the intuition that the object is falling at 9.8m/s^2 (constant acceleration downward)

Sounds like a Momentum - Impulse problem
Momentum = Mass * Velocity
Impulse = Force * Time
Mo = Im
===>
Mass * velocity = Force * Time
Then
Force = Mass * Acceleration
