1. A ball rolls off a 1.10-meter high table with an initial horizontal velocity of 3.3 m/s. Determine the time required for the
ball to fall to the ground and the horizontal distance between the table's edge and the ball's landing location.
2. A cannon ball is shot horizontally off a 25.0-meter high cliff and lands a distance of 141.0 meters from the edge of the
cliff. Determine the initial horizontal velocity of the cannon ball and the time it is in the air
3. A trebuchet launches a stone with an initial velocity of 32 m/s at an angle of 37-degrees from the ground. Determine the
time of flight, the horizontal distance, and the peak height of the stone.
