One pool ball is launched in the positive x direction with a speed of 2.5 m/s. A second, identical pool ball is launched in the negative x direction with a speed of 1.2 m/s. The two collide in a glancing collision (not head on) and the second ball is deflected directly in the positive y direction with a speed of 1.4 m/s. A. Determine the final velocity of the first ball. Give your answer in unit vector notation.
B. If the collision took place in a time interval of 0.080 s and the mass of the pool balls is 0.16 kg, determine the magnitude and direction of the force acting on the first pool ball.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
