A box in air moves down a rough slope from point P to point Q with its speed getting greater. The slope surface applies a frictional force of constant magnitude to the box. During the journey from P to Q, the magnitudes of its acceleration and the total resistive force on it change. Which row shows these changes?
- Amagnitude of acceleration increases; magnitude of total resistive force decreases
- Bmagnitude of acceleration decreases; magnitude of total resistive force decreases
- Cmagnitude of acceleration increases; magnitude of total resistive force increases
- Dmagnitude of acceleration decreases; magnitude of total resistive force increases
