x = xm * sin( omega-0 * t + :_alpha: )
dx/dt = v = xm * omega-0 * cos( :_omega:0 * t + :_alpha: )

mit  t0 = 0 ; omega-0=75/s ; xo = -22 mm ; vo= 8,3 m/s folgt:

I :     -22 mm = xm * sin( :_alpha: )
II:    8,3 m/s = xm* 75/s * cos( :_alpha: )

I/II:  -0,022/8,3 s = tan( :_alpha: ) / 75 * s
         :_alpha: = arctan(-0,022/8,3*75) = -11,2°
         xm = -22mm / sin(11,2°) = 113 mm
