In the figure, block A (mass 1.8 kg) slides into block B (mass 2.6 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are vAi = 5.5 m/s, vBi = 2.9 m/s, and vBf = 4.5 m/s. What is velocity vAf (including sign, where positive denotes motion to the right)?

Below is a picture of a collision between two objects. It starts with object A moving upwards towards object B. After the collision, object A moves purely in the x-direction and object B moves purely in the y-direction. If the initial velocity of object A is 3 m/s at and angle of 30 degrees as shown, find the final velocities of each object given mA = 10 kg and mB = 5 kg. Give your answer to three significant figures in standard units.
