Physics
1 answer:
kotegsom [21]4 years ago
6 0

The car covers a distance <em>d</em> after time <em>t</em> of

<em>d</em> = (2.8 m/s²) <em>t</em>²

Solve for <em>t</em> when <em>d</em> = 69 m:

69 m = (2.8 m/s²) <em>t</em>²

<em>t</em>² = (69 m) / (2.8 m/s²)

<em>t</em> ≈ 4.96 s

Why is the law of gravity an example of a universal law?
Greeley [361]

Answer:

A

Explanation:

The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.

Why is physics used to study the heat absorbed by the ocean?
Wewaii [24]

B
