A-LevelPhysicsDynamicsMay/June 2023Paper 1 Q91 Mark
A box in air slides with increasing speed down a rough slope from point P to point Q. [Figure 9.1] The slope surface exerts a constant frictional force on the box. As the box moves from P to Q, there are changes to the magnitudes of its acceleration and the total resistive force acting on it. Which row describes the 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
