A road running north to south crosses a road going east to west at the point P. Car A is driving north along the first road, and car B is driving east along the second road. At a particular time car A is 10 kilometres to the north of P and traveling at 80 km/hr, while car B is 15 kilometers to the east of P and travelling at 100 km/hr. How fast is the distance between the two cars changing ?

A ship A is moving Westwards with a speed 10 kmh ^(-1) and a ship B 100 km South of A , is moving Northwards with a speed of 10km^(-10) . The time after which the distance between them becomes shortest is :

A pendulum having a bob of mas m is hanging in a ship sailing along the equator from east to west. When the ship is stationary with respect to water the tension in the string is T_0 . a. Find the speed of the ship due to rotation of the earth about its axis. b. find the difference between T_0 and the earth's attraction on the bob. c. If the ship sails at speed v, what is the tension in the string ? Angular speed of earth's rotation is omega and radius of the earth is R.

A police jeep, approaching an orthogonal intersection from the northern direction, is chasing a speeding car that has turned and moving straight east. When the jeep is 0.6 km north of the intersection and the car is 0.8 km to the east. The police deteremine with a radar that the distance between them and the cae is increasing at 20 km/hr. If the jeep is moving at 60 km/hr at the instant of measurement, what is the speed of the car?

Relation between Time and Distance: A train runs constantly at a speed of 80km/hr. Draw a time – distance graph for this situation. Also find the distance covered in 5(1)/(2) hours.
