planet travels in a circular orbit around a star. The radius of the circular orbit is 3.01×1011 m and the orbital period is 4.27 years.  What is the magnitude of the centripetal acceleration of the

You're designing a highway so that the maximum centripetal acceleration on a curve is no more than 1.3 m/s^2. What is the minimum curvature radius to accommodate a 108 km//h maximum speed? This is about r=V^2/a, right? I have to convert km to meters, then hours to min to seconds.  Say the final is (30m/s)^2 /1/3 m/s^2 =692.3 m Does two sig figs mean that 692 is changed to 690 m or something else to get two sig figs?  Please explain?  If the answer is 62.3 then two figs mean 62. If 63.5, then 64.  But 692?

A jogger is running around a circular track that has a circumference of 472m. The magnitude of the centripetal acceleration of the jogger is 128cm/s2 .Calculate the jogger's speed in kilometer per hour

In a circular motion, if an object has a speed of 34.8m/s, and radius of the circular path is 80.2 m, what is the centripetal acceleration in m/s2?

A particle is moving in a circle of radius R. At t = 0, it is located on the x-axis. The angle the particle makes with the positive x -axis is given by 0 = At² + Bt³ What is the magnitude of the tangential acceleration, atan of the particle at a time t > 0? Express your answer in terms of R, t, A, and B as needed. What is the magnitude of the radial acceleration, larad of the particle at a time t > 0? Express your answer in terms of R, t, A, and B as needed.

In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 15.0 m in diameter. It is found that the pilot blacks out when he is spun at 30.6 rpm (rev/min). At what acceleration (in SI units) does the pilot black out? acceleration: 77.01 m/s? Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.858 If you want to decrease the acceleration by 22.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? percent of time change:

At the equator, the radius of the Earth is approximately 6370km. A jet flies at a very low altitude at a constant speed of v=222m/s Upon landing, the jet can produce an average deceleration of magnitude a=16.5m/s2 how long in seconds will it take the jet to circle the earth at the equator

In a circular motion, if an object has a speed of 35.5m/s, and radius of the circular path is 45.2 m, what is the centripetal acceleration in m/s?
