Your problem statement makes no mention of 30 and 60 degrees yet you introduce them in your solution. I think you should draw a diagram and do a better job of stating the problem.Np14 said:
Yes, your method has no logic to it. Why should the speeds be given by those expressions?Np14 said:

The conservation of momentum is a fundamental law of physics that states that the total momentum of a closed system remains constant over time, regardless of any internal changes or interactions within the system. In simpler terms, this means that the total amount of movement in a system cannot be created or destroyed, only transferred between objects within the system.
Rockets are a classic example of the conservation of momentum in action. As the rocket engine expels hot gases in one direction, the rocket is propelled in the opposite direction with an equal and opposite force, thanks to Newton's third law of motion. This applies to all stages of a rocket's launch, as well as its movement through space.
The conservation of momentum in a rocket is affected by a variety of factors, including the mass of the rocket, the velocity and direction of the ejected gases, and any external forces acting on the rocket, such as gravity or air resistance. All of these factors must be taken into account when designing and launching a rocket.
During a rocket launch, the conservation of momentum is maintained through the use of the rocket's engines. As the engines generate thrust and expel hot gases, the rocket is propelled in the opposite direction, conserving the overall momentum of the system. Additionally, the design of the rocket's stages and trajectory must also take into account the conservation of momentum.
The conservation of momentum has many practical applications in everyday life, including in transportation (such as rockets, cars, and planes), sports (such as throwing a ball or jumping), and even in the motion of celestial bodies in space. It is also used in the design and operation of machines, such as turbines and engines, and is a crucial concept in the field of physics and engineering.
