Alright, here we are.

What else would be needed?Ok I will draw a model to better depict what I am talking about.

This is pretty simple,but finding the correct formula does not seem to be that easy for me. How could I calculate wind speeds with only having the distance an object moved over a certain amount of time and the weight of said object? For example,winds caused a 600lb object to travel 30...

So here is a follow up question,how much energy would be required to propel this object at Mach 7 speeds?

Wow if I am correct is that over 8 billion kilograms of mass?

So I converted the ft^3 to m^3 and I have 1.04 million m^3* 7870kg/m^3=8184800000 kg/m^3.Did I do this right or do I have to remove the kg/m^3?

If an object the size of the empire statbuilding had iron density,what would be ... the mass of it? The estimated volume of the empire state building is 37 million cubic feet,how could I calculate the mass of this solid object if it had a density of Iron(which would be 7870 kg/m³)?

Thank you I just realized my error,but I was asking for general equations when I said "accelerating objects".

Ok,lets say an object is moving at a constant speed of Mach 7 for 20000ft. The weight for the object is 2000 lbs. What formulas could I use to calculate the energy for accelerating objects,or this one in particular?

Please read this carefully before answering,in fiction lasers are quite common and they seem to have the property to produce explosions.I am not asking if they exist,I am asking if with the right technology can laser beams produce explosions.Is this just some myth or is there some truth to...

The title basically summarizes this,and what Modern Day weapon/explosive could this be compared to?

Okay,in that case let's assume that the bat is a maple cylinder and let's assume the diameter is 2.75 inches and that the length of the thick part is 40 inches. The cylinder is also completely made of maple. With the density being 436 kg^3 where would i go from here on out to determine the...

Just a simple question,I would like to know how much force or energy it would take to break or obliterate a standard sized baseball bat made of maple. A hammer would be the tool for this. If possible could you explain the process used to calculate this and post the energy in joules?

Lets say that this is hypothetically possible;How much energy would be required to sink an Island the size of Palau(191 square miles)? Could this be calculated in Joules? What if a volcanic eruption was capable of doing this how much energy would it take to sink an Island of this size.

The thread title speaks for itself,I am wondering how I would be able to this. Ex: Volcano A erupts Volcano A yielded 1 kiloton of energy. ^^^How would I calculate that? ^^^
