Question
The following T/F questions all relate to the motion of a cartalong a track with the x-axis chosen parallel to the track All forces acting on the cart must be along thex-direction.TrueFalse Only the x-coordinate of the cart canchange.
TrueFalse If the object is moving on the positivex axis, the x-component of velocity must bepositive.
TrueFalse If the positive x-axis points to theright and the x-component of velocity is negative, thecart must be moving to the left.

TrueFalse
Explanation / Answer
All forces acting on the cart must be along thex-direction.False
Only the x-coordinate of the cart canchange.
True
If the object is moving on the positivex axis, the x-component of velocity must bepositive.
False
If the positive x-axis points to the right and thex-component of velocity is negative, the cart must bemoving to the left.
True
