the force diagram reflects the physical setup the walker is 15.0 m from either end; and is displacing the wire 1.0 m this means that the vertical component of the tension is one-fifteenth the tension in the wire (on BOTH sides) so the force exerted by the walker is 3675/15 * 2...

A tight-rope walker walks across a 30.0 m long wire tied between two poles. The center of the wire is displaced vertically downward by 1.0 m when he is half-way across. If the tension in both halves of the wire at this point is 3675 N, what is the mass of the tight-rope walker...

The acceleration rate "a" is the gravitational Weight force (M g) divided by mass (M). That is Newton's second law. But weight is proportional to mass, so the mass cancels out. acceleration = Mg/M = g When the effect of air resistance is included, objects that ...
