Example newton's 2nd law
WebIdentifying the first term on the left as the sum of the torques, and m r 2 as the moment of inertia, we arrive at Newton’s second law of rotation in vector form: Σ τ → = I α →. … WebThe total upwards force is therefore. F = + 240,000 N – 120,000 N = +120,000 N, and the initial acceleration, by Newton's 2nd law, is a = F/m = +120,000 N/12,000 kg = 10 m/s 2 = 1 g. The rocket thus starts rising with the same acceleration as a stone starts falling. As the fuel is used up, the mass m decreases but the force does not, so we ...
