    What is the spring constant for an elastic cord with varying weights?

    i have a similar problem so i didnt want to start a new thread, i hope there arent any feelings of thread jacking, but my problem is that i have the force and the k constant and an original length but i need to find the final length. would it be the force added to the k * x or multiplied like...

    Max height expressed with v, theta, and g

    wow! what a tedious mistake...it was the placement of the exponent and parenthesis that was wrong... thanx

    Max height expressed with v, theta, and g

    is my issue the placement of sin(theta) in the equation before i solve for h?

    Max height expressed with v, theta, and g

    ((1/2)m(v^2)*sin(theta))=mgh...then ((1/2)m(v^2)*sin(theta))/mg=mgh/mg...then the m cancels leaving me with (v^2*sin(theta))/2g=h

    Potential energy and turning points

    well you are starting from rest with U_i so it makes sense to me that what ever happens after would only be distributions of the energy between kintetic and potential so I would set the equation to what I am starting with
