Point 1 is PROBABLY higher up than point 4.
Another possibility is that on the way from Point 1 to point 4,
a lot of people are falling out of the coaster.
We have no way to tell, because you neglected to show us
the picture that goes with this question. It's important.
As we know that time period of simple pendulum is given as
T = 2π √L/g
here we know that
T = 3.8 s
now from above equation we know that
T² = 4π² (L/g)
now on rearranging the above equation we will have
L = gT² / 4π²
now plug in all data into it
L = (9.8) (3.8)² / (4) (3.14)²
so the length of the cable must be 3.6 m
