# Can you calculate average speed?

$$S_{1}, S_{2}$$ & $$S_{3}$$ are the different sizes of windows 1, 2 & 3 respectively, placed in a vertical plane. A particle is thrown up in that vertical plane. Average speed of the particle passing the windows may be equal if:

(Assume that the speed of the particle is sufficient so that it crosses all the windows.)
