... velocity would have to be 7.2 m/s. Since the horse generally slows down by about 2 m/s just before the takeoff stance, the approach velocity would have to be at least 9 m/s. This velocity usually requires galloping and results in lessening the ability of the horse to assume a symmetric stance for ta ...

... The action of a massless frictionless pulley is to change the direction of a T5 F tension. M Here F = T1 = T2 = T3 Equilibrium means S F = 0 for x, y & z For example: y-dir ma = 0 = T2 + T3 – T5 and ma = 0 = T5 – Mg So T5 = Mg = T2 + T3 = 2 F T = Mg/2 ...
