Answer:
It gets refracted.
Explanation:
When light beam travels through different mediums they refract i.e. they change their direction. Here the angle of incidence is less than 90°. After entering the glass slab the light beam will move towards the normal (a line drawn perpendicular to the interface of the two mediums). Thus the angle of refraction will be even lesser than angle of incidence.
Momentum in x-axis before collision: 4.5 x 1.5 = 6.75
Momentum in x-axis after collision: 1.5 x 2.1 x cos(30) + 3.2 x v x cos(30)
By the principle of conservation of momentum, these are equal:
6.75 = 2.73 + 2.77v
v = 1.45 m/s
