Telegraph poles occur at equal distances of 220 along a road and heaps of stones are put at equal distances of 300m along the same road. The first heap is at the foot of the first pole. How far from it along the road is the next heap which lies at the foot of a pole?

Let 10 vertical poles standing at equal distances on a straight line , subtend the same angle of elevation alpha at a point O on this line and all the poles are on the same side of O. If the height of the longest pole is h and the distance of foot the smallest pole form O is a then the distance between two consecutive poles, is

A car moving along a straight road with speed of 144 km h^(-1) is brought to a stop within a distance of 200 m. How long does it take for the car to stop ?

A tower of height b subtends an angle at a point 0 on the ground level through the foot of the tower and at a distance a from the foot of the tower. A pole mounted on the top of the tower also subtends an equal angle at 0. The height of the pole is

The electric pole subtends an angle of 30^(@) at a point on the same level as its foot. At a second point 'b' metres above the first, the depression of the foot of the tower is 60^(@) . The height of the tower (in towers) is equal to

A 20 m high vertical pole and a vertical tower are on the same level ground in such a way that the angle of elevation of the top of the tower, as seen from the foot of the pole, is 60^(@) and the angle of elevation of the top of the pole as seen from the foot of the tower is 30^(@) . Find : the horizontal distance between the pole and the tower.

A short linear object of length b lies along the axis of a concave mirror or focal length f at a distance u from the pole of the mirror. The size of the image is approximately equal to
