A flea is at point A on a horizontal turntable(adsbygoogle = window.adsbygoogle || []).push({});

15.7 cm from the center. The turntable is ro-

tating at 30.5 rev/min in the counterclockwise

direction. The flea jumps vertically upward to

a height of 5.18 cm and lands on the turntable

at point B. Place the coordinate origin at the

center of the turntable with the positive x axis

fixed in space and initially passing through A.

The acceleration of gravity is 9.8 m/s2 .

Find the linear displacement of the flea.

Answer in units of m.

I found the angle through which point A has rotated when the flea lands to be 37.63118767 degrees.

how would i find the displacement?

i tried finding the other angles by taking 180-36.63... and / 2 and then using the law of sines but it didn't work.
