SUMMARY
The discussion focuses on calculating the average net force acting on a bullet of mass 20g that strikes a fixed block of wood at a velocity of 320 m/s and embeds itself to a depth of 6.0 cm. The average net force can be determined using the formula F = Δp/Δt, where Δp is the change in momentum and Δt is the time taken to come to rest. Participants emphasize the importance of showing initial calculations to facilitate assistance, adhering to forum guidelines.
