Coefficient of Kinetic Friction: Calculating from Homework

Click For Summary
SUMMARY

The discussion focuses on calculating the coefficient of kinetic friction for a 4.30 kg block subjected to a horizontal force of 43.0 N. The acceleration of the block is determined to be 5.3 m/s² based on the provided speed versus time graph. Using the formula for friction, the coefficient of kinetic friction can be calculated by applying Newton's second law (f = ma) and the relationship between frictional force and normal force. The final calculation yields a coefficient of kinetic friction that quantifies the interaction between the block and the floor.

PREREQUISITES
  • Understanding of Newton's second law (f = ma)
  • Knowledge of frictional force concepts

Homework Statement


A 4.30 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 43.0 N. The figure gives the block's speed v versus time t as the block moves along an x axis on the floor. The scale of the figure's vertical axis is set by vs = 5.30 m/s. What is the coefficient of kinetic friction between the block and the floor?
