A .02 kg bullet moving directly upward at 850 m/s strikes and pass thought a block the mass of 7 kg initially at rest, off-center. Will the bullet emerge from the other end of the block wit a lower, higher, or equal speed compared to when it passes though the center of mass at 200 m/s? Briefly explain.

let B be the block of length d. let of be the resistive force / length applied by the block on the B bullet as it passes through Block ie f is the fess frictional force applied per unit length of the block as the bullet travels Then , Total force applied by block , F - fod acceleration imparted , as + = m fd m where mus the mass of bullet Now , let U be initial velocity , then using = > V = U + 2 ( 5 0 ) x d = 4 2- 240 - m 2 7 V = ux - 2 71 2 Y - we sign of a is due to m retarding nature of accelration 4 where I the is the final emerging velocity then .
