A 15g bullet moving horizontally with a speed of 300m s−1 enters a fixed wooden plank of thickness 4.0cm and emerges from the opposite face with a speed of 50m s−1. After emerging, the bullet rises vertically and finally comes to rest at the top of its trajectory.
Answer the following:
(a) Calculate the average resisting force exerted by the wood on the bullet while it is inside the plank.
(b) Find the additional vertical distance the bullet rises after leaving the plank.
