Force on object at angle to acceleration

Click For Summary

Homework Help Overview

The problem involves a scenario where a person is pushing a lawn spreader at an angle, seeking to determine the force required to achieve a specific acceleration. The subject area includes dynamics and force analysis, particularly focusing on the relationship between force, mass, and acceleration.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss calculating the required acceleration based on the provided information and emphasize the importance of analyzing the forces acting on the spreader. There is mention of using Newton's second law (F=ma) as a potential approach.

Discussion Status

The discussion is ongoing, with some participants attempting to clarify the necessary calculations and others expressing uncertainty about how to proceed after finding the acceleration. No consensus has been reached, but there is a focus on understanding the forces involved.

Contextual Notes

Participants are navigating the problem with limited information on the specific forces acting on the spreader and the implications of the angle of the handle. There is an indication of confusion regarding the application of relevant equations.

Homework Statement



Joe pushes down the length of the handle of a
10.5 kg lawn spreader. The handle makes an
angle of 42◦ with the horizontal. Joe wishes to
accelerate the spreader from rest to 1.35 m/s
in 1.3 s.
What force must Joe apply to the handle?
Answer in units of N.

Homework Equations


I can't even figure out which equation to use :(


The Attempt at a Solution

 
Physics news on Phys.org
Can you figure out what the acceleration should be based on what is given?

If you can, then you can analzye all the Forces on the spreader and make sure that the net force is in the same direction as the acceleration. Then it just comes down to F=ma

I can find acceleration, but not sure how else to finish it
 
anyone
