A car is travelling with a speed of "90m/s" due east. An observer is present at "5m" south of the line of motion.Find the angular velocity (in "rad/sec" ) of car relative to the observer when car is located northeast of him.

A boat is travelling with a speed of "27 km h"^(-1) due east. An observer is situated at 30 m south of the line of travel. The angular velocity of the boat relative to be the observer in the position shown will be

In the figure there is a long horizontal bridge over a river 75 m high from water surface. A strong man throws a stone in the parallel plane of the bridge. A observer in a car travelling on the bridge finds the stone going pass by the car while ascending and also while descending between two points on the road 30 m away. The car is travelling at a speed of 15 m/s. The stone is thrown from the bank of river just at the same level of water. What is the angle the velocity makes with the bridge when it goes past the car while ascending ?

A car is travelling at a velocity of 10 m/s and has a mass of 850 kg. What is its kinetic energy?

A car travels with a speed 12 m s^(-1) , while a scooter travels with a speed 36 km h^(-1) Which of the two travels faster?

A motor car A is travelling with a velocity of 20 m/s in the north-west direction and another motor car B is travelling with a velocity of 15 m/s in the north-east direction. The magnitude of relative velocity of B with respect to A is

A car is moving with a constant speed of 60 km h^-1 on a straight road. Looking at the rear view mirror, the driver finds that the car following him is at a distance of 100 m and is approaching with a speed of 5 km h^-1 . In order to keep track of the car in the rear, the driver begins to glane alternatively at the rear and side mirror of his car after every 2 s till the other car overtakes. If the two cars were maintaining their speeds, which of the following statement (s) is/are correct ?
