Yes, it's possible.

When I was 11, I planned on jizzing on my fingers and impregnating my best friends mother while she slept.

A bit arbitrary, but I think said best friend may have buttraped me in my sleep.

But that's another story for another time.

I know this is some baby tier shit.

But let's say I've got a cube that is 4 meters on every side (width, height, length), that is made of Iron

How much energy would it take to blow it up?

tl;dr babby tier mechanics

so v=d/t and a=d/t2, right? i have a task here now that says that i have an object with a velocity of 41.6m/s that linearly decelerates over a distance of 1500m and i need to find out the value of the acceleration
i feel like this is super easy but i just can't get it done
it's not even logical for me to divide by time to get from velocity to acceleration
also how do i handle the time value in these?

I'm looking to get into stargazing and such. I want telescope that will work for me in the Miami suburbs (basically I'm saying there is light pollution). My problem is cash. I found someone selling an Orion Star blast 6 telescope. From what I've read, I can't tell if 150mm aperture will be enough or not to get good images. He is selling it nearly new (in his words) for $200. Mind giving me some advice?
