1. The problem statement, all variables and given/known data A 8.0×10−2 kg arrow hits the target at 25 m/s and penetrates 3.8 cm before stopping. 2. Relevant equations What average force did the target exert on the arrow? What average force did the arrow exert on the target? 3. The attempt at a solution I found the force the arrow's exerting before it hits the target I think... (8*10^-2kg)*(9.8m/s^2)= 0.784N I don't know where to go from here though.
