A careless driver driving at 25 m/s hit a tree while fumbling with his phone. Assume the driver was in contact with the air bag for 0.22 seconds, and his upper body has 37 kg in mass, then how much average force (absolute value) does the air bag exert on the driver's upper body? Ignore gravity since the force was horizontal. Hint: use impulse and the change of momentum.
