A material point M of mass m = 0.1 kg hits the fixed base and bounces off. The velocity before impact v1 = 7 m / s forms an angle? 1 = 64 ° with the tangent Mx. The velocity v2 = 3.4 m / s after the impact forms an angle? 2 = 69 ° with the tangent. Determine the projection of the shock pulse on the axis Mx. (Answer -0.185)
