Final answer:
The provided question regarding an elastic collision between a proton and an alpha particle cannot be solved with exact outcomes due to the lack of specific details regarding kinetic energy distribution, angles, and conservation of momentum relationships in the given information.
Step-by-step explanation:
The student's question pertains to an elastic collision scenario in which a proton scatters off an initially stationary alpha particle. Due to the principles of conservation of momentum and energy, solving this problem involves using both conservation laws and applying them to the situation described. Unfortunately, without additional given information or assumptions, the detailed outcomes of such an elastic collision cannot be determined exactly, as the distribution of the kinetic energy between the proton and the alpha particle after the collision depends on specific angles and speeds which are not provided in this scenario.
However, under the general assumption of an elastic collision and the provided information, the following can be stated:
- The speed of the proton after the collision cannot be determined with the information given.
- Percent of kinetic energy retained by the proton could be found if the final velocity were known, but it is not provided in this case.
- The angle of deflection of the alpha particle would depend on the impact parameter and collision details, which are not specified.
- The speed of the alpha particle after the collision would result from the conservation of momentum, but cannot be calculated without further information.
Inelastic collisions, where kinetic energy is not conserved, would yield different final conditions, but for this scenario, the assumption of an elastic collision is typically used to apply conservation laws.
