Figure shows a string of linear mass density `1.0 g//cm` on which a wave pulse is travelling. Find the time taken by the pulse in travelling through a distance of 50 cm on the string . `(g = 10 m//s^(2))`
.

Text Solution

Verified by Experts

The tension in the string is `F=mg=10N. The mass per unit lent is mu=1.0 g cm^-1=0.1kgm^-1.` The wave velocity is therefoe `v=sqrt(Fmu)=sqrt((10N)/(0.1kgm^-1)=10ms^-1`. The time taken by the pulse in travellling through 50 cm is therefore `0.05s.

The brakes of a train which is travelling at 30 m//s are applied as the train passes point A. The brakes produce a constant retardation of magnitude 3lambda m//s^(2) until the speed of the train is reduced to 10 m//s . The train travels at this speed for a distance and is then uniformly accelerated at lambda m//s^(2) until it again reaches a speed of 30 m//s as it passes point B. the time taken by the train in travelling from A to B, a distance of 4 km, is 4 min.
