Finding initial velocity when given only mass and distance

AI Thread Summary
To find the initial velocity of a 1.428 kg textbook kicked 183 centimeters, the problem lacks sufficient information, such as time, acceleration, and force. The attempt at a solution incorrectly assumes a direct relationship between mass and acceleration, converting mass to force without considering the context of the kick. The discussion highlights that if the book is kicked straight up, mass becomes irrelevant, while a horizontal kick complicates the scenario due to varying friction. Participants emphasize the need for complete information to arrive at a unique solution. The conversation ultimately questions the assumption of additional forces acting on the book beyond gravity.

Homework Statement


A 1.428 kg textbook is kicked 183 centimeters, what is the initial velocity right as it left the foot?

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..

This problem makes sense if you assume that the book is kicked straight up in the air in which case the mass is irrelevant. If the book slides across a horizontal floor, a higher initial velocity than the expected answer can be compensated by a less slippery floor which means that there is no unique answer. Are you sure you have provided all the information that was given to you?

I second what kuruman said.
However, I'd like to ask you this: what made you think that there's a force other than that of gravity acting on the book?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
