Homework Statement
The problem:
A merry-go-round has a radius of 1.40m and a mass of 125kg. You may consider the merry-go-round to be a solid disk. A 60.0kg student stands on the outer edge of the merry-go-round, 1.40m from the center(the axis of rotation). It takes 3.00s for the...
Thanks for the help that you gave me, but we ended up going over the problem in class.
The solution:
We took the equation for torque for rotational and translational motion and put it together. I would explain the math, but I really don't completely understand it all. Starting equation is torque...
Okay I get what your saying about the relationship between the movement of the string and the movement of the spool. What I still don't understand is using Newtons laws or the angular acceleration equation. The equation for Newton's law is F=ma and changes to T=I X alpha. The acceleration...
I try and make it more clear sorry about that.
The Question from the homework:
A light string 4.00m long is wrapped around a solid cylindrical spool with a radius of 0.075m and a mass of 0.500kg. A 5.00kg mass is then attached to the free end of the string, causing the string to unwind from the...
