Question #342164

An arrow moving at 10 m/s is stopped by a target. If the arrow has a mass of 250 g and penetrates 4 cm into the target, what is the force exerted by the arrow on the target?

Expert's answer

The energy-work theorem says

"\\frac{mv^2}{2}=Fd"

"F=\\frac{mv^2}{2d}=\\frac{0.250*10^2}{2*0.04}=313\\:\\rm N"
