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 flat car of mass M with a child of mass m is moving with a velocity v_(1) . The child jumps in the direction of motion of car with a velocity u with respect to the car. Find the final velocities of the child and that of the car after jump.

In a car race, car A takes time t less than car B and passes the finishing point with a velocity of 12m//s more than the velocity with which car B passes the finishing point. Assume that the cars A and B start from rest and travel with constant acceleration of 9 m//s^(2) and 4 m//s^(2) , respectively. If v_(A) and v_(B) be the velocities of cars A and B, respectively, then

A car is going east wards with a velocity of 8m/s. To the passengers in the car, a train appears to be moving north wards with a velocity of 15 m/s. What is the actual velocity of the train:

Two cars A and B are moving on parallel roads in the same direction. Car A moves with constant velocity 30m//s and car B moves with constant acceleration 2.5 m//s^(2) . At , car A is ahead of car B and car B is moving with 12 m//s velocity . The distance travelled by car B until it overtakes car A is

Out of the two cars A and B car A is moving towards east with velocity of 10 m/s whereas B is moving towards north with a velocity 20 m/s, then velocity of A w.r.t B is ( nearly )

Car A starts from a point O and moves with constant velocity 9 m//s . After 2 s , another car B begins its journey from O and follows car A . If car B starts from rest and moves under constant acceleration 4 m//s^(2) , after how much time and at what distance from O the cars meet?
