A motor car is fitted with a convex driving mirror of focal length 20 cm . A second motor car is 6 m away from the driving mirror of the first car. Calculate (i) position of second car as seen in the first car mirror. (ii) if the second car is overtaking the first car at a relative speed of 15 m//s , how will its image be moving and in what direction ?

A motor car is fitted with a convex driving mirror of focal length 25 cm . Another motor car is 10 m away from the driving mirror of the first car. Calculate the position of second car seen in the driving mirror. If the second car is overtaking the first car with a relative speed of 20m//s , how fast will the image of the second car be moving ?

A car is fitted with a convex side-view mirror of focal length 20 cm. A second car 2.8m behind the first car is overtaking the first car at a relative speed of 15 m/s . The speed of the image of the second car as seen in the mrror of the first one is:

A convex, rearview mirror of focal length 20cm, is fitted in a car. A second car 2 m broad and 1.6m high is 6m away from the first car and overtakes the first car at a relative speed of 15 ms^(-1) , then the speed of the first car is

A driver stops his car at a red light. The car is fitted with side view mirror of focal length 10 m. An ambulance is approaching the car at a constant speed of 16 ms^(-1) . The speed of image of the ambulance, as seen by the driver in the side view mirror, when it is at distance of 50 m from the mirror will be

A naughty bird is sitting on top of a car. It sees another car approaching it at a distance of 12 km. The speed of the two cars is 60 km/hr each. The bird starts flying from the first car and moves towards the second car, reaches the second car and comes back to the first car and so on. If the speed at which the bird flies is 120 km/hr. The total distance travelled by the bird. (Assume that the two cars have a crash)
