HELP ME SOLVE THIS!! PLZZZ Volleyball: Court dimensions: 18m long - 9m wide. Net height: 2.23m for women
-If a volleyball is served with a diagonal velocity of 10m/s at an angle of 42◦ from the horizontal.
1. Does it hit the net?
2. Find out if it lands in the court or not.
3. What is the final (diagonal) velocity of the ball?
4. What is the landing angle of the ball?

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal. find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
