1. Suppose we roll a ball off a table, at a speed of 2.0 m/s. This means that the initial velocity is completely horizontal; there is no initial component of velocity in the vertical direction. The table is 1.3 meters high. (A) How much time does it take the ball to hit the ground after leaving the table? (B) How far does the ball travel horizontally: this is the distance "x" in the diagram?

2. An astronaut throws a rock from a cliff on the planetMars. He gives it an initial velocity of 20 m/s at an angle 34 degrees above the horizontal. The height of the cliff is 30 m, and the rock takes 8.0 s to hit the ground below the cliff. (A) How far from the base of the cliff did the rock hit? (B) What is the acceleration of gravity on Mars?
