Question

An object is dropped from the top of a building and is observed to take 7. 2s to hit the ground. How tall is the building?.

Answer 1

the height of the building is H=36 m.

What is The Law of Gravity?

According to Newton's law of gravity, every particle of matter in the universe is attracted to every other particle with a force that varies directly as the product of their masses and inversely as their distance from one another.

Properties of Gravity -

• It is a universal attractive force. It is directly proportional to the product of the masses of the two bodies.
• It obey inverse square law.
• It is the weakest force known in nature.

Examples of Gravity -

• The force that holds the gases in the sun.
• The force that causes a ball you throw in the air to come down again.
• The force that causes a car to coast downhill even when you aren't stepping on the gas.

v₀=0 m/s

H₀=0 m

g=10 m/s²

t=7,2 s

H - ?

$H= H_{0} + v_{0}t+\frac{gt^{2} }{2}$

H = 0 +0 × 7.2 + 10(7.2)²/2

H = 36m
