I have been working on this problem for an hour and have no clue what to do. I try to use equations such as v = v0 + at Velocity as a function of time delta x = (v0)(t) = 1/2(a)(t^2) Displacement as a function of time v62 = v0^2 + 2(a)(delta x) Velocity as a function of displacement but nothing as been working... A bullet is fired through a board 13 cm thick in such a way that the bullet’s line of the motion is perpendicular to the face of the board. The initial speed of the bullet is 350 m/s and it merges from the other side of the board with a speed of 250 m/s. a.Find the acceleration of the bullet as it passes through the board. b.Find the total time the bullet is in contact with the board. thank you to anyone that is will to help.
