# A block is projected up a ramp with an initial speed \( v_0 \). It travels along the surface of the ramp with constant acceleration \( a \). Take the positive direction of motion to be up the ramp. If the acceleration vector points opposite the initial velocity vector, which of the following MUST be true?

A block is projected up a ramp with an initial speed \( v_0 \). It travels along the surface of the ramp with constant acceleration \( a \). Take the positive direction of motion to be up the ramp. If the acceleration vector points opposite the initial velocity vector, which of the following MUST be true?

- **A.** The acceleration is negative.
- **B.** The velocity and acceleration have opposite signs throughout the block’s motion.
- **C.** The block slows down until it reaches a constant (terminal) speed.
- **D.** The block slows down until it comes permanently to rest at a maximum height on the ramp.
