Problem 1: An autographed baseball rolls off of a 0.56 m high desk and strikes the floor 0.65 m away from the desk. How fast was it rolling on the desk before it fell off? The acceleration of gravity is 9.81 m/s2.
Problem 2: A cat chases a mouse across a 1.4 m high table. The mouse steps out of the way, and the cat slides off the table and strikes the floor 1.4 m from the edge of the table. What was the cat's speed when it slid off the table? The acceleration of gravity is 9.81 m/s2.
Problem 3: A pelican flying along a horizontal path drops a fish from a height of 3.8 m. The fish travels 7.4 m horizontally before it hits the water below. What was the pelican's initial speed? The acceleration of gravity is 9.81 m/s2.
Problem 4: If the pelican was traveling at the same speed but was only 2.8 m above the water, how far would the fish travel horizontally before hitting the water below?
