First Locomotive train

A locomotive accelerates a train of identical railway carts. The carts are numbered consecutively with the cart next to locomotive having the number 1. The tension in the connection between the carts with numbers 4 and 5 is three times begger than the tension in the connection between the carts with numbers 14 and 15. What is the number of the last cart? there is no resistance to the train's motion.

A locomotive of mass m starts moving so that its velocity varies according to the law v=asqrts , where a is a constant, and s is the distance covered. Find the total work performed by all the forces which are acting on the locomotive during the first t seconds after the beginning of motion.

A train is moving at 30 m/s in still air. The frequency of the locomotive whistle is 500 Hz and the speed of sound is 345 m/s. The apparent wavelengths of sound in front of and behind the locomotive are respectively :-

A railroad train is travelling at 30 m//s in still air. The frequency of the note emitted by the node emitted by the locomotive whistle is 500 H_(Z) . What is the wavelength of the sound waves : (a) in front of the locomotive? What is the frequency of the sound heard by a stationary listener (b) behind the locomotive? (c) in front of the locomotive ? Speed of sound in air 344 m//s . (d) behind the locomotive ?

A railroad train is travelling at 30 m/s in still air. The frequency of the note emitted by locomotive whistle is 500 Hz. What is the frequency of the sound waves heard by a stationary listener (a) in front of the train and (b) behind the train? (speed of sound is 345m/s.)
