Question

If the positive x-axis points to the right and the x-component of velocity is negative, a cart must be moving to the left.

True

False

Answer 1

Answer: True

A negative velocity means the object is going the opposite way of the positive direction. So a negative x component velocity is pointing the opposite way (left) of the positive direction (right). You can think of it as the cart is backing up as it faces the positive direction.
