okay... in my University textbook, it says
a= V^2 - Vo^2
------------
2 Delta X X in this case being time right?
a= 0 - (45 m/s)^2
--------------
2(3)
a = -225 m/s^2
I thought it couldn't be negative acceleration, that's where I'm having trouble.
"You have the wrong force. 14.55 N is the net force while the puck is being hit. But after the puck leaves the stick (moving at 45 m/s), the only force on it is the friction acting to slow it down."
Hey everyone I'm a first time user and had the same problem with a similar question just...
