1. An iron ball is dropped from a flat platform (note: the initial velocity is zero). What is the velocity of the ballin m/s 1,6 s after it is dropped? Use g = 10 m/s². Do not include the units in your answer.

2. A ball on the table top is pushed to leave the table top horizontally with a velocity 6 m/s. It lands on the ground 0.4 s after it leaves the table top. At what distance in m from the edge of the table does it land? Do not include the units in your answer.

3. A ball on the table top is pushed to leave the table top horizontally with a velocity of 6 m/s. It lands on the ground 0.5 s after it leaves the table top. What is the height of the table top from the ground in m? g = 10 m/s². Do not include the units in your answer.

4.An iron ball is dropped from a flat platform (note: the initial velocity is zero). What is the distance in m the ball drops in a time period of 1.6 s? Use g = 10 m/s². Do not include the units in the answer.

5. A ball is dropped at the top of a building. Find the change in velocity in m/s at 1 s and at 4 s after the drop. Use g = 10 m/s². Do not include the units in the answer.
