MCQ
Shown here are the velocities and acceleration vectors for a man in several different types of motion. In which case is the man slowing down and turning to the right
- A
- ✓
- C
- D
✓
Answer
Correct option: B.
b
As the man is slowing down therefore, the acceleration component should be opposite to the velocity. so, the angle between velocity vector and acceleration vector should be obtuse.
As the man is slowing down therefore, the acceleration component should be opposite to the velocity. so, the angle between velocity vector and acceleration vector should be obtuse.
As the man is turning to the right therefore, the acceleration vector component should be towards the left side.
Thus, the correct option is $B.$
