Study the diagram of a block sliding down a ramp. Which arrow correctly represents the direction of the frictional force acting on the block?

A Arrow B (pointing up the slope)
B Arrow C (pointing vertically down)
C Arrow D (pointing perpendicular to slope)
D Arrow A (pointing down the slope)
Show Worked Solution

Worked Solution

Step 1: Determine the direction of motion (sliding down the slope). Step 2: Friction always acts in the opposite direction to motion. Step 3: Therefore, the arrow must point up the slope.

Correct answer: Arrow B (pointing up the slope)
