Well I meant I basically made gravitational potential energy equal kinetic energy and solved for v

Homework Statement Cylinder A (mass = 5kg) is released from rest at a height h =100mm above a spring of stiffness k = 1.8 kN/m. Determine, (i) the maximum compression of the spring, (ii) the spring deflection when the cylinder’s velocity is a maximum, and, (iii) the maximum velocity of the...

I should have mentioned, I did do that first step which gave me T = (2pi/root Gm) x r^3/2 . So the value I got for n was 3/2. Could you elaborate a bit more on what you mean later by working out the ratios of the T and r values? Because currently I can't think in my head how to do this without...

Homework Statement Deduce, from the equations employed in Q4 and Q5, the exponent n in the equation: T = k rn where k is a constant and T is the period of a satellite which orbits at a radius r from a massive object in space. Hence, how long is the “year” on Venus if its distance from the Sun...

That seems to be the only possible answer, thanks! :)

Hi everyone, first time poster here, I'm studying for a Materials exam, one of my weakest subjects and this question is causing me a lot of pain: Beryllium (Be) is a HCP metal with an atomic weight of 9 g mol-1 , an atomic radius of 0.112nm and a density of 1850 kg m-3 . Calculate its c/a ratio...
