Question: Force of Friction

  • #1
1. How much frictional force is acting on a 75 kg cart if a push of 220N results in an acceleration of 2.0m/s2?
(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???

Have a go at the problem mentioned in the hint. What force do you require to accelerate a 75 kg cart at a rate of 2.0 m/s^2

first find the force using mass * acceleration
then subtract the difference at easy as that.don't be scared because of your teacher.
