Unformatted text preview: outside while the other is half way in. Write the two vectors describing the children’s positions (in polar coordinates). The merry-go-round shown below is 6 feet in diameter. One child is hanging on at the outside while the other is half way in. The merry-go-round rotates one half turn, causing the latter child to slide to the outside. Write the two new vectors describing the children’s positions (in polar coordinates). The radius of the track below is 20m. A racecar is driving around the track. At some given moment, the car’s position is: Draw the car on the track.
