In a circus trapeze act, two acrobats fly through the air and grab on to each other, then together grab a swinging bar. One acrobat, with a mass of 60 kg, is moving at 3.0 m / s at an angle of 10^∘ above the horizontal, and the other, with a mass of 80 kg, is approaching her with a speed of 2.0 m / s at an angle of 20^∘ above the horizontal. What is the direction and speed of the acrobats right after they grab on to each other? | Numerade
