Question
A bullet is shot into a block of wood resting on a table. The bullet was stuck inside the block after the impact. The block slides along the table in a straight line and comes to a stop as a result of the collision. The mass of the bullet is 2.0g, the mass of the wood block is 56g, the velocity at instant of impact of the bullet was 140 m/s, the stopping distance of the table was 2.8m. Calculate the average frictional force that the surface of the table exerts on the wood block whilst the block is moving.
