The planet's radius is 5000000 m. The planet's period of rotation is 16 hours. How fast (in m/s) would a person standing at the equator be moving because of this rotation?

Expert Solution

How fast is our Earth rotating? More specifically, how fast are you moving due to the Earth's rotation on its axis? The answer always seems surprising, since as you observe the Earth from your residence, objects on the Earth don't seem to be moving that fast. In fact, some of the ancient astronomers (including Aristotle) believed that the Earth was stationary since there seemed to be no direct evidence and this was complicated by the fact that many believed that the Earth was at the center of the known universe and that everything, including the Sun, orbited it. Of course, we know now that the Earth is not stationary, is not at the center of anything, including our own Solar System, and does indeed rotate on an axis. We see this rotation every single day as the Sun, the Moon, planets and stars appear to move from east to west in our local skies every single day. The Earth's gravity keeps us rooted on the ground, thankfully! Here for this planet The speed of the man at equator will be =2*3.14*5000000/(16*3600)m/s =545.14m/s

The period of the Moon's rotation is the same as the period of its revolution: 27.3 days (sidereal). What is the angular momentum for each rotation and revolution? (Because the periods are equal, we see only one side of the Moon from Earth.)

Assuming the Eq.(3) in the text is valid, what period of rotation of a mass of 0.365 kg is to be expected for rotation radius of 0.140 m, if the outward pull which counters the spring inward pull for vertical mass-hanging string position at 0.140 m is delivered by a mass of 0.680 kg (pan included)? Use 9.810 m/s^2 for the acceleration of gravity. 2. If the quantities measured in order to verify Eq.(3) were obtained with values as in...

C++: how to do a bit rotation Left rotation of n = 11100101 by 3 makes n = 00101111 (Left shifted by 3 and first 3 bits are put back in last). Right rotation of n = 11100101 by 3 makes n = 10111100 (Right shifted by 3 and last 3 bits are put back in first. int left(int n, unsigned int d) { } int right(int n, unsigned int d) { }
