A missile of mass 4kg is fired through a stack of asbestos sheets 1.8m thick.If the missile approaches the asbestos with a velocity of 540m/s and emerges with a velocity of 270m/s,determine the average resistance R of the sheets.
I am quite uncertain what resistance means. However, the average force of resistance can be calculated.
solve for the average force of resistance.
