i) 1 m/s
ii) 2.5 m/s
iii) 5 m/s
iv) 10 m/s

Answer 1

Answer:

iv

Explanation:

We are given that the speed of the car is 2 m/s which implies, the car is approaching the truck with a speed of 2 m/s.

Hence the speed at which the image of the truck appears to approach the driver will be: 2\times2 = 4 m/s
