Can you help me with a difficult physics problem involving constant acceleration

First, let it be said that in my class only two equations are allowed to be used at this point in time. They are #1:Final Velocity = Initial Velocity + Acceleration x Timeand #2:Distance = Average Vel

Can I use a calculus position function in a physics problem about acceleration

yesterday i ran across a problem that said a car is at rest and accelerates at 2 meters per second^2. how long does it take the care to go 30 meters? The book used the physics formula and got 5.48 sec

Why does it sound louder when you pee into the water rather than on the side of the toilet bowl

Why does hitting h2o with pee sound different than hitting the ceramic. Im not familiar with acoustics so If someone could explain Id appreciate it.-Water consists of a bunch of loosely connected mole

Why does motion exist in this universe

Like by that i dont really mean that this is what i mean, i mean (lots of means)how can i get it into my mind what the hell motion ishow can i comprehend this, i mean how can an object just move from

If one atom of hydrogen were completely converted to energy

how big would the explosion be? in scale of tons of tnt-Not very big. The energy released will be just 9.3*10^8 eV. This is equivalent to 1.4*10^-10 Joules, or around 0.04 picograms of TNT-I arrive at

How is space different from matter

It seems to me that matter is just a highly quantized space (the so called fields). In this view vacuum is just a kind of matter with low quantization. Quantization itself must be a property of space
