Conservation of momentum so the total initial momentum in the system is equal to the total final momentum in the system. You must remember that if an object is travelling in the negative direction, you must put a negative sign for the velocity.
mv + mv = mv
plug in all the numbers
(0.0323)(4.50) + (0.078)(-1.12) = (0.0323 + 0.078)Vf
multiply everything together
0.14535 - 0.08736 = 0.1103Vf
simplify
0.05799 = 0.1103Vf
isolate for vf
Vf = 0.5257m/s east

Answer:
The refractive index of material of prism is 1.06.
Explanation:
Given that,
Angle of prism, A = 40 degrees
Angle of deviation,
We need to find the refractive index of material of prism. We know that the relation between angle of deviation, prism angle and the refractive index is given by :
is the refractive index of material of prism
So, the refractive index of material of prism is 1.06. Hence, this is the required solution.
