A straight highway leads to foot of the tower. A man standing at the top of the tower observes a car at an angle of depression of `theta`, which is approaching the foot of the tower with a uniform speed. Six seconds later the angle of depression is `phi`. Draw a diagram for this data and analyze.

A straight highway leads to the foot of a tower. Ramaiah standing at the top of the tower observe a car at an angle of depression 30^(@) . The car is approaching the foot of the tower with a uniform speed. Six seconds later, the angle of depression of the car is found to be 60^(@) . Find the time taken by the car to reach the foot of the tower from this point.

What change will be observed in the angle of elevation as we approach the foot of the tower?

There is a tower beside the road, Rahim standing at the top of the tower observes two cars A and B on either side of the tower at an anglea of depression 30^@ and 60^@ are approaching the foot of the tower with a uniform speed of 10m/sec and 5m/sec respe ctviely.If the height of the tower is 100sqrt 3 , then find the whihc car reaches the tower first and how many seconds the other car is late by the first one.
