Question
The diagram depicts a block sliding along a frictionless ramp. The eight numbered arrows in the diagram represent directions to be referred to when answering the questions.
Q4: The direction of the acceleration of the block, when in position I, is best represented by which of the arrows in the diagram?
1
2
4
5
None of the arrows; the acceleration is zero.
Q5: The direction of the acceleration of the block, when in position II, is best represented by which of the arrows in the diagram?
1
3
5
7
None of the arrows; the acceleration is zero.
Q6: The direction of the acceleration of the block (after leaving the ramp) at position III, is best represented by which of the arrows in the diagram?
2
3
5
6
None of the arrows; the acceleration is zero.
Explanation / Answer
Q4) 4
As the block is sliding, the direction of acceleration is along the ramp.
Q5) 1
In circular motion the direction of acceleration is always to wards the center.
Q6) 5
the direction of acceleration of a freely falling body always towards downward.
