Question

You will have TWO submissions for this problem. Select all that apply.

A glider of mass m, initially at rest, moves down a tilted, frictionless air track. The track makes an angle q with the horizontal. Which of these drawings correctly represent(s) the forces applied to the glider? NOTE that the "hash-marked" (//) arrow means that that force vector is shown along with its components. If the components are correctly determined, then this force diagram can be considered to be correct. A glider of mass m, initially at rest, moves down a tilted, frictionless air track.

Explanation / Answer

mg dowanwards and normal n perpendicular to slope .

so image 1. is one of answer.

now as block is moving along slope .

so we should get component of all forces along slope and pernpedicular to slope .

N is already perpendicu;ar .

compos of mg along = mgsintheta

perpendicular = mgcostheta

so image 3 is also a answer
