A body of mass 9 kg moves in a (counterclockwise) circular path of radius 5 meters, making one revolution every 9 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component. A. Compute the centripetal force acting on the body.

\( \frac { 2 x y ^ { 2 } } { 6 x } , \frac { y } { 9 } \)

Romeo needs to see the love of his life, Juliet. The only open window is on the second foor 25 feet above the ground. Romeo will need to horrow a ladder from one of Juliet's neighbors. There is a bush along the edge of h house, so Romeo will have to place the ladder 10 feet from the house. If the neighbor's ladder is 28 feet tall, wh Romeo's ladder reach juliet? Explain your answer.
