4) Two objects, A with mass of 3.0 kg and object B with mass of 1.0 kg, move on a frictionless horizontal surface. Object A moves to the right at a constant velocity of 5.0 m/s, while object B moves to the left at a constant velocity of -2.0 m/s. They collide and bounce off one another (a perfectly elastic collision). Object A is now moving to the left at -2.0 m/s, A. Determine the total momentum of the system (both objects) before the collision B. What is the velocity of object B after the collision?

Atrain is traveling at 30.0 m/s relative to the ground in still air. the frequency of the note emitted by the train whistle is 262 hz. the speed of sound in air should be taken as 344 m/s. what frequency (f approach) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? what frequency (f recede) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and receding from it?
