A horizontal turntable is rotating clockwise at a speed of 35.5 rev/min. The turntable is oriented in the xy-plane of a coordinate system, with the origin at the center of the turntable, and the +z-axis vertically upward. A point on the turntable is labeled A, and this point is 12.0 cm from the center of the turntable. A jumping spider sits at point A, and at the instant point A crosses the +x-axis (that is, when the position of the spider is 12.0î cm), the spider jumps straight up to a height of 2.00 cm. At takeoff, it gives itself no horizontal velocity relative to the turntable. A short time later, the spider lands back on the turntable. (Express your answers in vector form.)   (a)Find the position (in cm) of point A at the instant the spider lands back on the turntable. rA = ______cm (b)Find the position (in cm) of the spider at the instant it lands back on the turntable. rspider, final = _____cm

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
