In a collision of particles in two dimensions, mass m1( = 0.27 kg) is initially moving to the right along the x-axis at velocity 2.9 m/s while mass m2( = 0.47 kg) is at rest (prior to the collision). The angles given in the figure are: θ1 = 52 deg and θ2 = 39 deg. What is the magnitude of the velocity of m2 after the collision? Express your answer in m/s but enter only the numerical part.
