1) Mass m1 = 0.7 kg moves with constant velocity v1i = 2.0 m/s along the x-axis 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 x-axis and the direction of motion of the two masses after the collision. (Answer in degrees.)
