Light bounces off the surface of an object in a process called

The speed of the object at its' final location is; 38 m/s

What is work energy theorem?

For the first force, we are given;

Force; F₁ = 220i + 320j - 120k

Initial Position; r₁ = 13i - 19j - 3k

Final Position; r₂ = 18i - 11j - 8k

Thus; Displacement; Δr = r₂ - r₁

Δr = 18i - 11j - 8k - (13i - 19j - 3k)

Δr = 5i + 8j - 5k

From work energy theorem, we know that;

F₁ * Δr = ¹/₂m(v₂² - v₁²)

We are given v₁ = 2.5 m/s and m = 60 kg. Thus;

(220i + 320j - 120k) × (5i + 8j - 5k) = ¹/₂ * 60(v₂² - 3.5²)

4260/30 = v₂² - 3.5²

1420 = v₂² - 12.25

Solving gives v₂ = 37.85 m/s

For the second force, we are given;

Force; F₂ = 150i + 230j - 220k

Initial Position; r₁ = 18i - 11j - 8k

Final Position; r₂ = 22i - 17j - 3k

Thus; Displacement; Δr = r₂ - r₁

Δr = 22i - 17j - 3k - (18i - 11j - 8k)

Δr = 4i - 6j + 5k

From work energy theorem, we know that;

F₂ * Δr = ¹/₂m(v₂² - v₁²)

Now,  v₁ = 37.85 m/s and m = 60 kg. Thus;

(150i + 230j + 220k) × (4i - 6j + 5k) = ¹/₂ * 60(v₂² - 37.85²)

320/30 = v₂² - 37.85²

10.67 = v₂² - 1,432.6225

Solving gives v₂ = 38 m/s

coal is the correct answer

So far we have been emphasizing how, at a fundamental level, the generation and propagation of gravitational and electromagnetic radiation are basically quite similar. This is a major point in demystifying gravitational waves. But, on a more practical level, gravitational and electromagnetic waves are quite different: we see and use electromagnetic waves every day, while we have yet to make a confirmed direct detection of gravitational waves (which is why they seemed so mysterious in the first place).

There are two principal differences between gravity and electromagnetism, each with its own set of consequences for the nature and information content of its radiation, as described below.

Answer:

1) Gravitational force and electromagnetic force both are field forces which means both forces exerted from long range of distance and we do not require any physical contact to apply these type of forces.

2) Now we also know that

both the forces are inversely depends on the square of the distance between two charges or two masses

so both forces follow inverse square law.

Now two ways they are alike is

1) gravitational force never exist in form of repulsive force while electromagnetic force is either repulsive or attractive.

2) Gravitational force is independent of the medium between two masses while electromagnetic force is dependent on the medium between two charges

Inertia increases as mass increases.

Explanation:

Inertia is the resistance of an object to any change in motion. Inertia is proportional the mass of the object: in fact, as we experience in common situations, the larger the mass of an object, the more difficult it is to change its motion.

A simple example: while it is quite easy to stop a tennis ball thrown towards us, we know that it is not so easy to stop a large truck travelling towards us with the same speed: the reason for that is that the truck has much more mass than the tennis ball, so it has much more inertia. Therefore, inertia increases as mass increases.
