Joseph jogs from end A to the other B of a straight 300m road in 2min 30 sec and then turn around and jogs 100m back to point c in another 1 minute. What are Joseph's average speeds and velocities in jogging (a) from A to B and (b) from A to C ?

A car is moving along a straight line, say OP in Fig. It moves from O to P in 18 s and returns from P to Q in 6.0 s. What are the average velocity and average speed of the car in going (a) from O to P ? and (b) from O to P and back to Q ?

A passenger arriving in a new town wishes to go from the station to a hotel located 10 km away on a straight road from the station . A dishonest cabman takes him along a circuitous path 23 km long and reaches the hotel in 28 min . What is (a) the average speed of the taxt , (b) the magnitude of average velocity ? Are the two equal ?

A farmer moves along the boundary of a square field of side 10 m in 10 sec. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from what position?

Two poles of equal height are standing opposite to each other on the either side of the road which is 80 m wide. From a point P between them on road, the angle of elevation of the top of a pole is 60^(@) and the angle of depression from the top of another pole at point P is 30^(@) . Find the heights of the poles and distances of the point P from the poles.

Places A and B are 160 km apart on a highway. One car starts from A and another from B at the same time. If they travel in the same direction they meet in 8 hours. But if they travel towards each other, they meet in 2 hours. Find the speed of each car. Let P and Q be the cars (1) starting from A and B respectively.

A and B are two infinitely long straight parallel conductors.C is another straight conductor of length 1 m kept parallel to A and B as shown in the figure.Then the force experienced by C is
