Did Problem 2 similar to the first. P.E.i = m*g*h P.E.i = 1kg * 9.6m/s * .3m P.E.i = 2.94J K.E.i = 1/2 * m * (v)^2 K.E.i = 1/2 * 1kg * (.8m/s)^2 K.E.i = .32J K.E.f = 1/2 * m * (v)^2 K.E.f = 1/2 * 1kg * (1.2m/s)^2 K.E.f = .72 Need P.E.f P.E.i + K.E.i = P.E.f + K.E.f 2.94J +...

Yes, I tried but I had no way to know if the answers I got are correct so I sent the answers I had. Which as it turns out had been wrong. But I think I finally got Problem 1. P.E.i = 4.9J K.E.i = 0J P.E.f = 1.96J K.E.f = ? K.E.i + P.E.i = K.E.f + P.E.f 0J + 4.9J = 1/2 * 1kg * (v)^2...

I emailed the teacher and asked for help but he provided answers: Problem #1: 2.42 m/s^2 Problem #2: .259 m When I input the values from the chart I do not get the answers he provided. So, I am not sure what I am doing wrong. Does anyone else get the same solutions mentioned above?

I will have to dust off my algebra book to move the variables around as the information in the chart is provided. I will try it in the morning see what I get. Thanks for the help!

But that will only provide data in Joules and not a velocity or height? Thank you

Homework Statement I have a homework assignment that I am stuck on using the attached table. Problem 1: I have to find the velocity when given the mass and height. Problem 2: Then I have to find the height when given the velocity and mass. Homework Equations P.E. = m*g*h K.E. =...
