Explanation:
It is given that, the height of a certain tower is 862 feet i.e to reach on the ground the object should travel, s = 862 feet
The distance traveled by a freely falling object is given by :



t = 7.34 seconds
So, the object will take 7.34 seconds to fall to the ground from the top of the building. Hence, this is the required solution.
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
Work = force x distance. So the answer would be 200x50=10000 joules
