**[SOLVED] angular acceleration, displacement**

## Homework Statement

A flea is at point A on a horizontal turntable 9.3 cm from the center. Place the coordinate origin at the center of the turntable withthe positive x-axis fixed in space and initially passing through A. THe turntable is rotating at 34 rev/min in the counterclockwise direction relative to the fixed coordinate system. Then the flea jumps upward (meaning that it adds only its own vertical velocity when it jumps, not to its horizontal velocity) to a height of 4.9 cm in the fixed coordinate system and lands on the turntable at point B. The acceleration of gravity is 9.8 m/s^2.

1) Find the linear displacement of the flea in the fixed coordinate system.

2) Find the angle relative to the fixed coordinate system through which point A has rotated when the flea lands.

3) Find the distance of point B from the origin in the fixed coordinate system when the flea lands.

4) What angle does the radius drawn through B make with the fixed x-axis when the flea lands.

5) what is the linear speed of the flea relative to the fixed coordinate system after it lands
