(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A bullet traveling horizontally at a speed of 350 m/s hits a board perpendicular to the surface, passes through it, and it emerges on the other side at a speed of 210 m/s. If the board is 4 cm thick, how long does the bullet take to pass through it (in seconds)?

2. Relevant equations

X(t) = Vt + x(i)

3. The attempt at a solution

My problem is not knowing which formula to use. Thank you
