From the question we are told

A neutron (mass 1.01 u) strikes a deuteron (mass 2.01 u), and they combine to form a tritium nucleus (mass 3.02 u). The neutron's initial velocity was 23.5i^+14.4j^Mm/s and the tritium nucleus leaves the reaction with velocity 15.1i^+22.6j^Mm/s.

Select the correct d euteron's velocity. Express your answer in terms of i^ and j^. Use the 'unit vector' button to denote unit vectors in your answer.

Generally the equation for the momentum law   is mathematically given as

,   =  27.11 10⁶ m/s

Explanation:

This exercise should be solved using the concepts of momentum, as the cores are combined the shock is inelastic.  

Let us form a system constituted by the neutron, deuteron and tritium for this system all the forces during the crash are internal so that the moment is conserved. Let us remember that the moment is a vector quantity, so each component must be kept independent of the others.  

We establish a nomenclature  

Neutron  

mₙ = 1.1 u  

vₙ₀ = (235 i ^ 14.4 j ^) 10⁶ m/ s  

= 2.01 u

X axis  

p₀ₓ = mₙ vₙ₀ₓ +  

=  

Axis y  

= mₙ +  

=  

Let's write the conservation equations of the moment and solve  

p₀ₓ =

mₙn vₙ₀ₓ + = vTfx  

= - mₙ vₙ₀ₓ  

=  

mₙ + =  

= - mₙ = 3.02u 15.1 - 1.01u 23.5  

2.01 = 21.867  

= 21.867 / 2.01  

= 10.88 10⁶ m / s  

2.01u = 3.02u 22.6 - 1.01 14.4  

= 54.71 10⁶ /2.01

= 27.11 10⁶ m/s

it takes about 30 days for it to break down

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
