1. A bullet (m1 = 0,01 kg) hits a ball hanging on a thread (m2 = 1kg) and stays in he ball (therefore new system = m1 + m2) and pushes the whole system into the height of 0,2m (max potential energy, Kinetic energy = 0) Calculate the speed initial speed of bullet (v) and the initial speed of...
Hi guys, I've been struggling with this proof for some quite time now. I have to prove that
x + y + xy = 36; has no solution in Natural numbers.
I've started with proving that both x and y have to be even numbers (which is easy to prove) but now I'm going in circles. The problem is, that...
