Two cars are moving in the same direction with the same speed ( = 30km/hr ). They are separated by a distance of 5 km. What is the speed of a car moving in the opposite direction if it met these cars at an interval of 4 minutes?

A car moving with a speed of 126 kmh^-1 is brought to stop within a distance of 200 m. What is its retardation and how long it takes for the car to stop ?

A car covers first half of the distance between two places at a speed of 40 km/hr and the second half at 60 km/hr. What is the average speed of the car?

A car moving along a straight highway with a speed of 126 km h^-1 is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop?

Work Problem related to speed, distance and time Two places A and B are at distance 160km . Two cars starting form tha same place and moving in the same direction meet after eight hours. Again moving in the oppoosite directions from A to B. The cars meet each other after one hour. Find the speed of the cars.

A police van moving on a highway with a speed of 30 km h_ 1 fires a bullet at a thief’s car speeding away in the same direction with a speed of 192 km h^-1 . If the muzzle speed of the bullet is 150 m s^1 with what speed does the bullet hit the thief’s car ? (Note: Obtain that speed which is relevant for damaging the thief’s car).

A man throws balls with the same speed vertically upwards one after another at an interval of 2 seconds. What should be the speed so that more than two balls are in the sky at any time? ( g = 9.8ms^-2 )

Two towns A and B are connected by a regular bus service with a bus leaving in either direction every T minutes. A man cycling with a speed of 20 km h~1 in the direction A to B notices that a bus goes past him every 18 min in the direction of his motion, and every 6 min in the opposite direction. What is the period T of the bus service and with what speed - (assumed constant) do the buses ply on the road?

Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m s~1 collide and rebound with the same speed. What is the impulse imparted to each ball due to the other?
