The force exerted by a certain bow on an arrow decreases linearly after the arrow is released by the archer, starting at a value Fs= 275 N when the bow is fully drawn and decreasing to Fs = 0 as the arrow leaves the bowstring. The tail of the arrow moves from s= 0 to s = 0.500 m as the arrow is shot. Find the final speed of the arrow, which has a mass of 30 gm.
