A bullet of mass 10g is fired horizontally with a velocity of 300ms-1 into a block of wood of mass 290g which rests on a rough horizontal floor. After impact, the block and the bullet move together and come to rest when the block has travelled a distance of 15m. Calculate the coefficient of sliding friction between the block and the floor.

A body of mass m1 moving with velocity u, collides with another body of mass m2 at rest. If they stick together after collision, find the common velocity with which they move

Initial momentum = m₁u + m₂ x 0 = m₁u

Final total momentum = (m₁ + m₂)v

By conservation of linear momentum

m₁u = (m₁ + m₂)v
