Kinematics of droplet during the sneezing using/not a mask.

Recently, there is hot debate wether wehave to use mask or not during the covid-19 pandemic.

I tried to make a very simple kinematics model about sneezing.

1. In the case of without mask, I use very simple projectile motion
2. With Mas, I use simple projectile motion and inelastic collision with 'mask'.

There are so many simplifications in this model. However, the maximum distance of the ejected droplet without mask is 2.6 m if the high of mouth is 1.6 m.
