1) Mass m1 = 0.7 kg moves with constant velocity v1i = 2.0 m/s along the xaxis and collides with mass m2 = 1.8 kg, which moves with velocity v2i = 3.4 m/s, as sketched below. After the collision, m1 and m2 stick together. Find the angle, θ, between the xaxis and the direction of motion of the two masses after the collision. (Answer in degrees.)
