The relation between the x and y-components is given by:
Correct answer: C. y = ax - bx2
- A. y = ax2 - bx
- B. y = ax + bx2
- C. y = ax - bx2
- D. y = bx - ax2
Explanation
The correct relation between the x and y-components in motion in two dimensions is given by the formula y = ax - bx2. This formula shows that the y-component is dependent on the x-component with a linear (ax) and quadratic (bx2) relationship.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
