Using the parenthesis method, convert the local value of the acceleration of gravity (g=9.798 m/s2) to the referent mph/s.

a person swings a rock around on a string, causing it to sweep out in a circle of radius 1.8m. If the rock travels at a constant speed of 18.7 m/s, what acceleration does it experience?

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 28.0 ° north of the equator. Re (a) v = Units ac = Units (b) v = Units ac = Units

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 =

Calculate the numerical values of the accelerations experienced by objects near the surface of Earth due to the following. Assume uniform circular motion a = w²r. a) Earth's gravity (A: 9.8m) b) Earth's rotation about its own axis (4:0.034) c) Earth's revolution around the Sun. (A: 0.006)

A bicyclist is at the bottom of a hill with a speed of 30ft/s. After traveling 600 ft on the road, she reaches the top of the hill with a speed of 15ft/s. Her total acceleration at the top of the hill is 1.3ft/s^2. Assuming acceleration is constant, what is the radius of curvature of the hill?
