Just a real sort question...

Is it possible for a number to actually be infinity and if not, wouldn't saying a number is infinity actually mean it is approaching infinity?

You are in a hot-air balloon that, relative to the ground, has a velocity of 6.2 m/s in a direction due east. You see a hawk moving directly away from the balloon in a direction due north. The speed of the hawk relative to you is 1.8 m/s. What are the magnitude and direction of the hawk's velocity relative to the ground?

For three years Magellan and his flotilla of ships circumnavigated the globe.On Tuesday, Sept. 1519 their journey started at Sanlucar de Barrameda, a port city on the Atlantic coast of Spain, and traveled southwest to the coast of Brazil. From there, they continued down the coast of Brazil and headed through the Strait of Magellan (right above Cape Horn), and west through the Pacific. They reached the Pilippine Islands. After sailing southeast away from the Philippines, the remainder of the crew finally arrived at the Spice Islands (known today as the Moluccas) and took a load of cloves. Then they ventured west through the Indian Ocean, through the Cape of Good Hope, and north, where they docked at Sanlucar de Barrameda, their place of departure, on Saturday, Sept. 6, 1522. Yet the Spaniards insisted that is was the 7th. How could this be? Antonio Pigafetta, a venetian from the ship, checked his detailed logbook that he had marked their daily positions in, and it said the 6th. How?

If a net force acts on an object, the object's velocity will change.
In order not to slow down, a car moving at a constant velocity needs a small net force applied.
During the collision of a car with a large truck, the truck exerts a greater force on the car than the car exerts on the truck.
The net force which acts on an object which remains at rest is zero.
If an object's speed does not change, no net force is acting on the object.
If two objects are under the influence of equal forces, they have the same acceleration.

Perceived color is from the fact that an object absorbs and reflects color. If an object is red, will it fade from the sunlight faster than an object that is blue? Because a red object has to absorb the higher frequency blue, and the blue color absorbs the low frequency color red? The rays will break the chemical bonds of the dye and cause it to fade.
