So far I have this: vbwx= 4.40c0s(28) = 3.88496409 vbwy= 4.40sin28 = 2.065674876 vpwx= 4.4ocos28 vpwy= 4.40sin28 +2.02 Find Square root of vpx^2 + vpy^2 = 5.43? Im confused as to whether we add the 2.02 to the sin28 or the cos28 though, did I do it right? Also, not sure how to find the...

Thanks! Could I get the link to that post, I am new to the website so I'm not sure how to find it

launch phase

The masses are given in the physics sketch too one ball is 0.0285 kg and the other is 0.067 kg

The video is a different one that shows the same thing but with two different balls (a big ball and a small ball) and the question is which of the two balls loses more initial elastic energy. And we have to determine this mathematically using energy equations.

he said my answer was good up to the second step, I just need to add one more thing and he told us to consider the friction

Wf is the work of friction and yes, there is kinetic energy and gravitational energy, I included those in the LOL diagram and my equation

I calculated Wf and it seemed to be bigger for the larger ball (in my mathematical solution in the image). But I don't know if that's the right answer.

maybe in the initial elastic energy? I am not sure, this is just what my teacher asked

This is the video: I think when he pulls back there is friction from the wood and ball

Two balls were shown (a large and small ball) and the question is " Which one of the two loses more energy" due to friction as it is pulled back on the launcher. I calculated the work of friction done, above my conclusion statemment you can see, our teacher said that "you can't directly...

I would like to know what the last remaining step is or if there's another way to find the answer maybe.

I got 12/12 on the above part^ And as for the mathematical solution below I got 5/6 and then 2.5/3 for the conclusion.
