MCQ
Which graph shows best the velocity-time graph for an object launched vertically into the air when air resistance is given by $| D | = bv?$ The dashed line shows the velocity graph if there were no air resistance.
- A
- ✓
- C
- D
✓
Answer
Correct option: B.
b
The velocity will first decrease with a larger rate when it will be going up and it will not increase at a very big rate when it will fall down. Also it will come to rest before it comes to rest without any air resistance.
