Finding the magnitude of net force

Click For Summary
SUMMARY

The net force on a 725 kg block accelerating at 5.10 m/s² at an angle of 14.0 degrees can be calculated using the equation F = M * A. To find the net force, it is essential to decompose the gravitational force into components parallel and perpendicular to the inclined plane. The gravitational force acting on the block is 725 kg * 9.81 m/s², which must be resolved into two components based on the given angle. This approach allows for the accurate calculation of the net force acting on the block.

PREREQUISITES
  • Understanding of Newton's Second Law (F = M * A)
  • Basic knowledge of trigonometry for angle decomposition
  • Familiarity with gravitational force calculations
  • Concept of forces on inclined planes
NEXT STEPS
  • Learn how to decompose forces on inclined planes using trigonometric functions
  • Study the effects of friction on net force calculations
  • Explore the concept of normal force in physics
  • Practice problems involving net force and acceleration at angles
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and forces, as well as educators seeking to clarify concepts related to net force and inclined planes.

How do you find magnitude of net force given mass, angle, and acceleration? I have a mass of 725 kg, an acceleration of 5.10 m/s squared and an angle of 14.0 degrees.

The only equation I'm given is F=M*A but I don't know how to apply it when I have an angle as well.

I guess your mass is on an incliened plane with angle 14 degrees.

If so, then if there's no friction you have just gravitational force downwards, decompose this force into two Parts, one Normal to the surface (but opposite to the Normal force), the other parallel to the plane of inclination.

Hopes that helped somehow, your post doesn't seem to be very clearly written.
 
Hm okay. I'm sorry I didn't clearly state the question. The original question asks, "Find the magnitude of net force (i.e. the sum total of all the forces) on the following object:
A 725 gram block that is accelerating at 5.10 m/s2 at an angle of 14.0 degree relative to horizontal.
