Which of the following is not in uniform circular motion? CD in a CD player spinning at 45 rpm orbiting satellite that speeds up near the earth and slows down far away jet fighter making a high-speed loop at 600 m/s merry-go-round that is 10.0 m in diameter and rotating at 2 rpm

Answer:

Orbiting satellite that speeds up near the earth and slows down far away.

Explanation:

A uniform circular motion can be defined as the movement or motion a body that is in circular path and it must be in constant speed. The direction of motion of such a body can be known by taking tangent at its every position.

Now according to given options:

  • CD in a CD player in spinning at a constant speed and motion is circulatory. So it is in uniform circular motion.
  • The speed of satellite is varying with respect to the distance from earth, so it is not in uniform circular motion.
  • The speed of jet fighter is also given (constant), So it is also in uniform circular motion.
  • Merry-go-round has constant rotations per minute so it will also be in uniform circular motion.

I hope it will help you!
