A flea is at point Ⓐ on a horizontal turntable, 10.0 cm from the center. The turntable is rotating at 33.3 rev/min in the clockwise direction. The flea jumps straight up to a height of 5.00 cm. At takeoff, it gives itself no horizontal velocity relative to the turntable. The Ilea lands on the turntable at point Ⓑ. Choose the origin of coor-dinates to be at the center of the turntable and the positive xaxis passing through Ⓐ at the moment of takeoff. Then the original position of the flea is 10.0i cm. (a) Kind die position of point Ⓑ when die Ilea lands. (b) Find die position of point Ⓑ when the flea lands.

Solution Summary: The author determines the position of point A when the flea lands and the angular speed of the turn table.
A flea is at point Ⓐ on a horizontal turntable, 10.0 cm from the center. The turntable is rotating at 33.3 rev/min in the clockwise direction. The flea jumps straight up to a height of 5.00 cm. At takeoff, it gives itself no horizontal velocity relative to the turntable. The Ilea lands on the turntable at point Ⓑ. Choose the origin of coor-dinates to be at the center of the turntable and the positive xaxis passing through Ⓐ at the moment of takeoff. Then the original position of the flea is 10.0i cm. (a) Kind die position of point Ⓑ when die Ilea lands. (b) Find die position of point Ⓑ when the flea lands.
This figure (Ja = 24.0 m/s?) represents the total acceleration of a particle moving clockwise in a circle of radius r = 3.00 m at a certain instant of time.
30.0°
(a) For that instant, find the radial acceleration of the particle.
m/s? (toward the center)
(b) For that instant, find the speed of the particle.
m/s
(c) For that instant, find its tangential acceleration.
m/s? (in the direction of the motion)
A turntable has a diameter of 40.0 cm. It rotates at a rate of 40 revolutions per second (rps) thanks to the action of a motor. It slows its speed evenly to 15 rps in 10 seconds. Calculate:
d) The magnitude of the total acceleration vector.e) The angle, in radians, for the turns in that time interval.f) The arc length traveled by a point on the saucer in that time interval.
A child is holding a string with a ball tied at the end. The childspins around in a circle causing the ball to travel in uniformcircular motion. While doing this, the 1.3 m long string makesa 48.8◦angle below horizontal. What is the tangential speedof the ball?
Solution provided is incorrect. Answer should be v=2.7m/s
