A satellite moves on a circular earth orbit that has a radius of 6.7 x 105 m. A model airplane is flying on a 15-m guideline in a horizontal circle. The guideline is parallel to the ground. Determine the speed (m/s) of the plane such that the plane and the satellite have the same centripetal acceleration.

The figure below shows an object initially at point A traveling in the +x-direction. It turns in a circular path at constant speed until it is traveling in the +y-direction at point C. The quarter-circle arc from A to C is 245 m in length, and the particle moves from A to C in 38.0 s. Point B on the path is 35.0° below the x-axis. 0 35.0⁰ (a) What is the speed of the object (in m/s)? m/s Need Help? (b) What is the magnitude and direction of the acceleration when the object is at point B? (Enter the magnitude in m/s² and the direction in degrees counterclockwise from the +x-axis.) magnitude m/s² direction Read It counterclockwise from the +x-axis

The earth rotates once per day about an axis passing through the north and south poles, an axis that is perpendicular to the plane of the equator. Assuming the earth is a sphere with a radius of 6.38 x 10 m, determine the speed and centripetal acceleration of a person situated (a) at the equator and (b) at a latitude of 65.0 ° north of the equator

A scooter, starting from rest, accelerates at 2.72m/s^2 on a circular track with a 205m diameter. What is the elapsed time, in seconds, at which the centripetal acceleration of the scooter has the same magnitude as its tangential acceleration?

A ball on the end of a string is whirled around in a horizontal circle of radius 0.254 m. The plane of the circle is 1.31 m above the ground. The string breaks and the ball lands 2.16 m away from the point on the ground directly beneath the ball’s location when the string breaks. The acceleration of gravity is 9.8 m/s2 . Find the centripetal acceleration of the ball during its circular motion.

A red car has a speed of 17.6 m/s and is driving on a circular track with a radius of 111 m. A blue car has a speed of 10.3m/s and is driving on a circular track with a radius of 55 m. What is the ratio of the centripetal acceleration of the red car to that of the blue car? ared/ablue =
