**1. How much frictional force is acting on a 75 kg cart if a push of 220N results in an acceleration of 2.0m/s**

(hint: how much force would have been required to accelerate the cart at that rate if there were no friction - the extra force is the amount needed to overcome friction)

^{2}?(hint: how much force would have been required to accelerate the cart at that rate if there were no friction - the extra force is the amount needed to overcome friction)

**I honestly have no idea how to solve this, im in basic highschool physics and my teacher's teaching styles don't work for me. Can anyone please help???**
