I guess we are talking about the ball hanging from a hook and 46 degrees above vertical? Ac = m v^2/r T = tension T sin 46 = m v^2/r T cos 46 = m g so tan 46 = v^2/(rg) v^2 = r g tan 46 but r = 3 sin 46 so v^2 = (3 sin 46)(9.8)tan 46

math (am i correct)
Record = m (year -1920) + b where year -1920 = t so R = m t + b 46.9 = m (0) + b so b = 46.9 in 1990, t = 1990 - 1920 = 70 so 45.5 = m (70) + 46.9 m = -.02 so R = -.02 t + 46.9 for 2003 for example t = 2003 - 1920 = 83 so R = -.02(83)+46.9 R = 45.24
