Answer:3/5 vExplanation:The computation of speed will the alpha particle have after the collision is shown below:-

In a perfectly elastic the kinetic energy and collision the momentum are considered.

The velocity of the particles defines the below equation:As we know that

Here, we consider A is the alpha particle and B is the proton and now by the above values we can solve the equation which is below:-Therefore the correct answer is
