256bits replied to the thread High School Does acceleration affect impact energy vs constant velocity?.All the answers given are really quite good to point you in the right direction, especially noting that the consequences of including an... -
haruspex replied to the thread Magnitude of buoyant force in fluids of different densities.That would have been clearer, yes. But consider.. 1. "Cars of velocities v1 > v2 > v3 are driven from A to B. Rank the cars in order... -
