A 20kg child moving at 3.0m/s tangentially jumps onto the edge of a merry-go-round at rest. The merry-go-round has a mass of 250kg and a radius of 2.25m. Assume the merry-go-round behaves as a uniform disk and the child behaves as a point mass. Determine the angular velocity immediately after the child lands in revolutions per minute. A) 0.86
B) 1.76
C) 2.17
D) 3.85
E) 5.29

time (seconds)

answer: 0 meters/second^2

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
