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 a same direction with a speed of 192 km h^(-1). If the muzzle speed of the buller is 150 m s^(-1), with what speed does the bullet hit thief’s car? . [...]

Two parallel rail tracks run north-south Train A moves north with a speed of 54 km h^(-1) and train B moves south with a speed of 90 km h^(-1). What is the a. relative velocity of B with respect to A? b. relaity of a monkey running on the roof of the train A against [...]

Suppose you are reding a bike with a speed of 10 m s^(-1) due relative to a person A person A who is walking on the ground towards east. If your friend B walking on the ground due west measures you speed as 15 m s^(-1), find the relative velocity between two refence frames A [...]

A person walks up a stationary escalation in t 1 ​ second. If he remains stationary on the escalator, then it can take him up in t 2 ​ second. If the length of the escalator is L, then a. Determine the speed of man with respect to the escalator. b. Determine the speed of [...]
