Question

if a pulse is generated in a slinky of length 2m and it moves four times in the slinky with in a time span of 10 second the speed of the pulse is

Answer 1

is it 0.2 m/s!!! i am not sure
#shimmers

Answer 2

length = 2 m
time of movement = 4 times
therefore
total distance = 2*4 = 8 m
time = 10 sec
so
speed = distance / time = 8/10 = 0.8 m/s

i hope it helps.............
