Question

A flea is at point A on a horizontal turntable
13.4 cm from the center. The turntable is rotating at 37.8 rev/min in the counterclockwise
direction. The flea jumps vertically upward to
a height of 6.33 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.

Q:What angle does the radius drawn through B
make with the x-axis when the flea lands?
Answer in units of ◦

Q:What is the linear speed of the flea after it
lands?
Answer in units m/s

Answer 1

try to find the cordinates at the time of landing...take ref. as zero during the strt of flight...if the table reches the same spot angle will be zero...or it may vary accordingly..cal. the time from eq. v=ut+1/2at^2

Answer 2

hey don't forget to take care of the flea's velocity as it leaves the table.
