We must write down laws of conservation of momenta and energy.
For the law of conservation of momenta will we will use two axes. One will be x-axis that will correspond to the east, and the other one will be y-axis corresponding to the north. Jack will be marked as 1 and Jill will be marked as 2.
Law of conservation of energy:
This will give us Jill's velocity after the colision.
Law of conservation of momenta:
We will use the second equation to get the angle at which the Jill is traveling:
When we plug all the number we get:
Please note that this is the angle below the x-axis.

Answer:
162.78 m/s is the most probable speed of a helium atom.
Explanation:
The most probable speed:
= Boltzmann’s constant =
T = temperature of the gas
m = mass of the gas particle.
Given, m =
T = 6.4 K
Substituting all the given values :
162.78 m/s is the most probable speed of a helium atom.
