yep ok Moment of Empty mug = mh/2 When the water has depth h, the mass is 3m. Take mass of water as km where 0\leq k \leq3 therefore height of water = hk/3 and moment of water is mass x distance from base = km*(hk/3)*1/2 = ((k^2)mh)/6 Moment of the whole system = (m+km)Y (where Y =...

Homework Statement Ok, there's a cylindrical mug of mass m. When full of water it has a mass 4m. Assuming the base of the mug has no mass, how full is the water in the mug when the centre of mass is the closest to the base? (as a proportion of the height of the mug I'm guessing) The...

Homework Statement Typical bungee jumper. Rope has natural length h, spring constant k, man has mass m. The safety limit for the max acceleration of the man is 3g. Derive an expression for x double dot, and show mg *greater or same than* kh/4 Homework Equations Well I'm sure everyone...
