The answer is a Telescopic gauge.
A Telescopic gauge is a tow point transfer gauge that can be used with an outside micrometre to measure inside diameter.
What is Telescopic gauge?
- Telescoping gauges are indirect measuring devices used to determine the internal diameter of a bore, hole, groove, slot, or other similar structure.
- A handle, two telescopic rods, and a locking screw make up this T-shaped tool.
- Telescopic gauges with two plunging telescopic rods are available, as are those with only one.
- Telescopic gauges are used to measure the internal diameter of a bore, hole, or groove with a diameter of up to 150mm (6′′), such as camshaft bearings or connecting rod bore bearings. They are primarily used by mechanics to measure the bore size of a crankcase in an engine with moving pistons.

Just ignore the horizontal component
if you have a vertical displacement of 15m, 0ms^1 initial velocity, end velocity is ignored, we know the acceleration due to gravity as 9.81ms^2 so we can work out the time using SUVAT
S=15
U=0
V=?
A=9.81
T=?
S=UT + 0.5 AT^2
UT=0
therefore,
S=0.5AT^2
rearrange to:
T=SQR (2S/A)
T = 1.75 seconds
