Bob has gone for an early morning run at a constant speed of 2.96 m/s. Unfortunately he has been distracted while trying to change his Spotify playlist from his Kpop playlist (mainly BTS and Blackpink) to an all Macklemore playlist. While changing playlists, Bob runs into a tree.
After hitting the tree, Bob bounces back with a speed of 0.459 m/s. This Bob-tree interaction lasted 0.981 s.
If Bob has a mass of 50.0 kg, what is the magnitude of the average force Bob feels from the tree?
