Find the total time that the bullet is in contact with board

Reference no: EM13646268

An indestructible bullet 2.00 cm long is fired straight through aboard that is 10.0 cm thick. The bullet strikes the board with aspeed of 430 m/s and emerges with aspeed of 290 m/s. (To simplify, assumethat the bullet accelerates only while the front tip is in contactwith the wood.)

(a) What is the average acceleration of thebullet through the board?

m/s2

(b) What is the total time that the bullet is in contact with the board?

(c) What thickness of board (calculated to 0.1 cm) would it take tostop the bullet, assuming that the acceleration through all boardsis the same?
