Aperson on horseback is on a drawbridge which is at an angle θ = 20.0° above the horizontal, as shown in the figure. the center of mass of the person-horse system is d = 1.00 m from the end of the bridge. the bridge is ℓ = 6.91 m long and has a mass of 1,980 kg. a cable is attached to the bridge 5.00 m from the hinge and to a point on the wall h = 12.0 m above the bridge. the mass of person plus horse is 1,260 kg. assume the bridge is uniform. note that the drawing is not to scale and you may not assume that the cable is perpendicular to the bridge. (due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in webassign.)
