73. We apply the conservation of linear momentum to the x and y axes respectively. 11 1 2 2 2 1 2 cos cos 0 sin sin if f ff mv θθ =+ =− We are given 5 2 1.20 10 m/s f v , 1 64.0 θ and 2 51.0 . Thus, we are left with two unknowns and two equations, which can be readily solved. (a) We solve for the final alpha particle speed using the y -momentum equation: () ( ) 5 22 2 5 1 16.0 1.20 10 sin 51.0 sin 4.15 10 m/s 4.00 sin 64.0 f
