Net Force Question with no velocity or time given.

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem concerning the net force acting on a ball of mass 0.6 kg in motion, with specific emphasis on the absence of velocity and time information. Participants are exploring the implications of these missing parameters in the context of net force calculations.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to identify the relevant forces acting on the ball, particularly questioning the role of gravity and whether it should be considered alone or in conjunction with weight. There is uncertainty about how to proceed without velocity or time data.

Discussion Status

The discussion is active, with participants raising questions about the forces involved and the implications of gravity on the net force. Some guidance has been provided regarding the consideration of gravity, but no consensus has been reached on how to calculate the net force without additional information.

Contextual Notes

Participants note the lack of specific details such as initial and final velocities or time intervals, which are critical for applying the net force equation effectively. The problem constraints are acknowledged but remain unresolved.

[SOLVED] Net Force Question with no velocity or time given.

Homework Statement


A ball of mass 0.6 kg flies through the air at low speed, so that air resistance is negligible.

What is the net force acting on the ball while it is in motion?

Homework Equations


Fnet = m(change in velocity/change in time)

The Attempt at a Solution


Can't attempt because I don't know how to find the change in velocity or the change in time. They don't tell beginning time or ending time, the tell the weight, and neither the velocity. I know the vector will look like <0, y, 0> but I don't know how to calculate the y value.

You already know you can ignore air resistance. What other forces act on the ball?
 
You have gravity acting on the ball as well, and that's it. The gravity is pulling the ball down in the y direction. Would it be gravity? Or the weight plus gravity?
 
Is gravity -9.8 N? If it is then that should be the answer right?
