The rear view mirror of a car is a plane mirror A driver is reversing ...
Since the mirror is a plane mirror , so the speed in which the car is reversing is same the speed in which we are seeing in the mirror about the approaching bus. So the speed at image of the truck appears to approach when the driver sees this in the rear mirror of car will be (2+2) m/s , i.e 4 m/s
The rear view mirror of a car is a plane mirror A driver is reversing ...
Explanation:
Speed of the Image:
- When the driver is reversing his car at a speed of 2m/s, the speed of the image in the rear view mirror is not affected by the driver's speed.
- The image of the truck parked behind the car will appear to move towards the driver at the same speed as the truck's actual speed.
Reasoning:
- The image in the plane mirror appears to be the same distance behind the mirror as the object is in front of it.
- As the driver reverses the car, the distance between the truck and the driver decreases, causing the image of the truck to appear to move towards the driver.
Visual Explanation:
- Imagine the driver is reversing the car and the truck is stationary behind the car.
- As the driver moves closer to the truck, the image of the truck in the rear view mirror will appear to move towards the driver at the same rate of 2m/s.
Conclusion:
- The speed at which the image of the truck appears to approach the driver is 2m/s, regardless of the driver's speed. This is because the image in the rear view mirror reflects the actual distance between the driver and the object behind the car.
