Biography

I'm Alex. I'm a sophomore studying Physics and Computer Science at the University of Central Florida. I took a variety of AP courses, so I have a lot of experience with AP test prep. One day, I hope to be an astrophysicist and it is my dream to work at NASA. I'm also a passionate learner. As I continue to learn everything I can, I wish to be able to pass along my knowledge and teach others in a way that they can understand.

The center of gravity of an irregular object is shown in Fig. $11.20 .$ You need to move the center of gravity 2.20 $\mathrm{cm}$ to the left by gluing on a tiny $1.50-\mathrm{kg}$ mass, which will then be considered as part of the object. Where should you attach this additional mass?

Consider the equation $v=\frac{1}{3} z x t^{2} .$ The dimensions of the variables $v$, $x,$ and $t$ are $\left.[\mathrm{L}] / \mathrm{L}^{\mathrm{T}}\right],[\mathrm{L}],$ and $[\mathrm{T}],$ respectively. The numerical factor 3 is $\mathrm{di}-$ mensionless. What must be the dimensions of the variable $z$, such that both sides of the equation have the same dimensions? Show how you determined your answer.
