Could you guys help me with these questions.Please show the full working out and solutions.
1. A loaded gun is being fired by a stationary robber. As the bullet exits, the gun has a velocity of 50m/s. If the mass of the bullet is 50g and the mass of the gun is 1500g. Calculate the velocity of the gun after the bullet is being fired.
2. Objects A and B are travelling towards each other along a straight road. Object A of mass 30kg, moves with the velocity of 5m/s. Object B of mass 20kg moves with a velocity of -7m/s. After the collision the objects rebound from one another, object A is 6m/s. Calculate the velocity of object B.
3. Objects A and B are travelling towards each other along a straight road. Object A of mass 30kg, moves with a velocity of 5m/s. Object B, of mass 20kg, moves with a velocity of 7m/s. After collision the objects stick together. Calculate the velocity
