1) A plane flying horizontally at 55.0 m/s drops an aid package to a village below. The pilot wants to drop the package a distance of 125 m horizontally before the village. How high off the ground must the plane fly to get the package to the village directly?

2) A cannonball is shot out of a cannon with a horizontal velocity component of 40 m/s [right] and a vertical velocity component of 20 m/s [up]. If the cannon is sitting at the top of a 100 m high cliff, how far horizontally will the cannonball travel?

3) A ball is thrown at an angle of 53^o above the horizontal at an unknown velocity. We do know that the ball has an initial horizontal velocity of 82 m/s, and that the ball returns to the ground. How far did the ball go horizontally?

4) What is the final velocity of an object that has been shot out of a cannon with a horizontal velocity component of 18 m/s [right] and a vertical component of 21 m/s [up]? The object lands 2.0 m above the starting point and 70.0 m away.

5) A tennis ball hits with a an initial velocity of 25 m/s [10^o above the horizontal] starting from a height of 2.1 m, lands on the ground. There is a net 15 m away and 0.9 m high. Will the ball clear the net at its peak, and by how much?
