Sorry for taking so long to get back to you! It's been a busy week. I seem to understand what you have explained so far.

radians=degrees x pi/180? Or am I supposed to be making an actual estimate here?

I'd get height=sin theta x distance. I don't understand how it plugs into the total energy formula though.

all I can think of is sin theta=height/distance

alright thank you! I am still unsure of where to go from there and how to connect that with v,w,h and a.

So I am picturing the right triangle? d is therefore the hypotenuse and the height is opposite the angle of inclination. I'm sorry this process is taking so long! The question is just really strange to me.

I know KE rotational= 1/2Iw^2 KE linear=1/2mv^2 PE=mgh I'm not sure where to go from there.

thanks for the help! I have no values so that is why I am having problems I think. I know the moment of inertia of a cylinder is I=1/2MR^2. I'm still lost though.

Oh thank you! That makes much more sense. I'm still really confused about how it relates to the slope and y-intercept though.

ahhh sorry I misread. R is radians but I don't have radians given.

R is the radius (2.25 cm).

Homework Statement I'm currently doing a lab that focuses on a pulley and have got stuck on on part. The goal here is to use the data from the Atwood’s pulley experiment to test the validity of (m1-m2)g=(m1+m2+1/R^2)a. In this equation, take the quantity (m1−m2)g as the y variable and the...

The height of the first bounce was 0.799 m. Therefore half that distance is 0.3995 (Where KE and PE are equal). I then took this is used it in the PE equation. The mass of the ball is not changing however so I don't see that it's needed. Therefore PE=mgh PE=0.3995m x 9.8 PE=3.92 Therefore...

Homework Statement I am currently working on a lab that deals with a bouncing ball where I need to find the KE and impulse yet I have no mass given. Homework Equations PE=mgh KE=1/2mv p=mv The Attempt at a Solution I have calculated KE by first finding the PE in the middle of the...
