How to Calculate Frictional Force on a Moving Cart?

Click For Summary
SUMMARY

The discussion focuses on calculating the frictional force acting on a 75 kg cart when a push of 220 N results in an acceleration of 2.0 m/s². To determine the frictional force, one must first calculate the net force required to accelerate the cart using Newton's second law (F = m * a), which equals 150 N (75 kg * 2.0 m/s²). The frictional force is then found by subtracting this net force from the applied force, resulting in a frictional force of 70 N (220 N - 150 N).

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Basic knowledge of mass and acceleration
  • Ability to perform simple arithmetic calculations
  • Familiarity with the concept of friction in physics
NEXT STEPS
  • Study Newton's second law of motion in detail
  • Learn about different types of friction (static, kinetic)
  • Explore real-world applications of friction in physics
  • Practice solving problems involving forces and motion
USEFUL FOR

High school physics students, educators seeking alternative teaching methods, and anyone interested in understanding the principles of force and motion.

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, I am in basic high school 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.
