Question

what is the velocity of pulse for the slinky when it takes 5 sec to travel from point A to B and back to A.The distance between A and B is 5m​

Answer 1

distance=5m time=5s

speed=distance \ time = 1m/s

Answer 2

Given :

Distance between point A and B , d = 5 m .

Time taken by pulse to reach point B through point A , t = 5 sec .

To Find :

The velocity of pulse for the slinky .

Solution :

We know , velocity of an object is given by :

$V=\dfrac{Distance }{Time}$

Putting value of distance and time in above equation .

We get , $V=\dfrac{5 \ m}{5\ s}=1\ m/s$

Therefore , the velocity of pulse is 1 m/s .
