A small object moves at constant speed in a horizontal circle of radius 0.540 m. If the object makes two complete revolutions in one second, what is the magnitude of the acceleration of the object?

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 106 m, determine the speed and centripetal acceleration of a person situated (a) at the equator and (b) at a latitude of 50.0° north of the equator. (a) v = (b) v= ac = i i i i Units Units Units Units 0 Re P

A bicycle, starting from rest, accelerates at 1.67m/s2 on a circular track with a 185m diameter.What is the elapsed time, in seconds, at which the centripetal acceleration of the bicycle has the same magnitude as its tangential acceleration?

A woman rides a carnival Ferris wheel at radius 22 m, completing 4.1 turns about its horizontal axis every minute. What are (a) the period of the motion, and the magnitude of her centripetal acceleration at (b) the highest point and (c) the lowest point?

A particle rotates in a circle of radius 80 cm at an anglular speed of 9 rad/s. What is the magnitude of its centripetal acceleration?

A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 35 m. The runner starts the race at a constant speed. If she completes the 200 m dash in 22.6 s and runs at constant speed throughout the race, what is the magnitude of her centripetal acceleration (in m/s2) as she runs the curved portion of the track?

A Ferris wheel with a radius of 24.0 m is turning about a horizontal axis through its center as shown in the figure. The speed of a passenger on the rim is constant and equal to 6.00 m/. What is the magnitude and direction of the passenger's acceleration as she passes through the (a) lowest point in her circular motion and by the highest point in her circular motion? (c) How much time does it take the Ferris wheel to make one revolution? (d) Include a diagram of the passenger on the Ferris wheel at both locations and clearly indicate both the velocity and acceleration vectors of the passenger in the diagram

The earth orbits the sun once every  π x 107 s at a distance of  1.5 x 1011 m.  Assuming uniform circular motion, what is its centripetal acceleration?

A woman rides a carnival Ferris wheel at radius 18 m, completing 4.8 turns about its horizontal axis every minute. What are (a) the period of the motion, and the magnitude of her centripetal acceleration at (b) the highest point and (c) the lowest point? (a) Number i Units (b) Number i Units (c) Number i Units

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
