A bullet of weight W₁ traveling at v₁ strikes the wooden block of weight W₂ and exits the other side at v₂ as shown. Determine the speed of the block just after the bullet exits the block. Also, determine the average normal force on the block if the bullet passes through it in time Δt , and the time the block slides before it stops. The coefficient of kinetic friction between the block and the surface is μ_k.
