Had Galileo dropped a cannonballfrom the Tower of Pisa, 179 ft above the ground, theball’s height above the ground t sec into the fall would have beens = 179 - 16t2. About how long would it have taken the ball to hit the ground?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
