Block pushed up 35degree incline (frictionless)

Click For Summary
SUMMARY

A block with a mass of 2.0 kg is pushed up a frictionless incline at a 35-degree angle by an applied force of 20 N. To determine the block's acceleration, one must analyze the forces acting on it, specifically the gravitational force component acting down the incline. Using Newton's second law (F=ma), the resulting acceleration can be calculated by subtracting the gravitational force component from the applied force and dividing by the mass of the block.

PREREQUISITES
  • Understanding of Newton's second law (F=ma)
  • Knowledge of free body diagrams
  • Basic trigonometry for resolving forces along an incline
  • Familiarity with gravitational force calculations
NEXT STEPS
  • Calculate the gravitational force component acting down the incline using trigonometric functions.
  • Learn how to draw and interpret free body diagrams for inclined planes.
  • Explore the effects of friction on inclined planes in physics.
  • Study the relationship between force, mass, and acceleration in various contexts.
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding dynamics on inclined planes.

1. a block is pushed up a 35 degree incline (no friction) by an applied force. If F= 20N and m= 2.0kg, what is the magnitude of the resulting acceleration of the block?



2. not sure?
f=ma




3. don't know where to start. It has been a long time since physics

Welcome to PF.

Start by drawing a free body diagram.

You have gravity of g acting straight down. What component of gravity then is acting down the incline?

And how might this weight component act with respect to the force pushing up the incline?
