Question

A pulse was created in a slinky of length 4 m. It was observed that it returned, after reflection, at the point of creation 6 times in10 s. Calculate the speed of the pulse.

Open in App

Solution

Total distance covered by the pulse, $d = 2 \times 6 \times 4 m = 48 m$
Total time taken, $t = 10 s$
So speed of the pulse, $v = \frac{d}{t} = \frac{48}{10} = 4.8 m / s$

Q. A student fixes a slinky to one end of a smooth table . He gives a transverse horizontal jerk to create a pulse in the slinky. The pulse completes four to and fro journeys along the length of the table . The time taken for the journey is 2.8 sec . The length of the table is 25 cm . What is the speed of the pulse moving on the slinky?
