1. The problem statement, all variables and given/known data A 1.428 kg textbook is kicked 183 centimeters, what is the initial velocity right as it left the foot? 2. Relevant equations fk-ma/W Vf^2=Vo^2*2aΔx 3. The attempt at a solution We were given no time, no acceleration, and no force. I'm completely at a loss! this is what I have, but I don't think it's correct: I found acceleration by applying the rule: 1N is a force that when applied to object with mass of 1kg, produces an acceleration of 1 m/s^2. So i converted the 1.428 kg into 14.0 N, which (hopefully) means the acceleration is 14 m/s^2 then I used the second equation to solve for initial velocity. Now, this could be completely wrong, and I will venture to guess that it is. So if maybe someone could double check the work here, or even possibly come up with a completely different way of solving it..
