A person travelling by a car moving at `100 km h^(-1)` finds that his wristwatch agress with the clock in a tower A. By what amount will his wristwatch lag or lead the clock on another tower B, 1000km (in the earth's frame ) from the tower A when the car reaches there?

A person travels by a car at a speed of 180 kmh^(-1) . It takes exactly 10 hours by his wristwatch to go from the station A to the station B . (a) What is the rest distance between the two stations ? (b) How much is taken in the road frame by the car to go from the station A to the station B?

A car is travelling at a velocity "10 km h"^(-1) on a straight road. The driver of the car throws a parcel with a velocity 10sqrt2km h^(-1) with respect to the car, when the car is passing by a man standing on the side of the road. If the parcel is to reach the man, the direction of throw makes the following angle with the direction of motion of the car

Due to a tower clock 80m high the loudness of sound heard at 8km from the clock was 30dB then what is the loudness heard at the base of the clocktower.

A car is moving at 24 km *h^(-1) towards east and another car is moving north at 18 km *h^(-1) . Find the relative velocity of the second car with respect to the first.

A 1000 kg car is travelling at 108 km/h when the brakes are applied. If the car stops in 10 m, find the stopping force .

A car A is travelling from west at 50 km/hr and car B is travelling towards north at 60 km//hr . Both are headed for the intersection of the two roads . At what rate are the cars approaching each other when car A is 0.3 kilometers and car B is 0.4 kilometers from the intersection ?
