A 30.0-g arrow is shot by William Tell through an 8.00-cm-thick apple sitting on top of his son’s head. If the arrow enters the apple at 30.0 m/s and emerges at 25.0 m/s in the same direction, with what force has the apple resisted the arrow?

First, convert g to kg and cm to m.

30.0 g 0.0300 kg 8.00 cm 0.0800 m

Next, find the acceleration of the arrow before finding the force

This is the force that the apple exerts on the arrow. It is negative because its direction is opposite to the arrow’s direction of motion.
