haha. i love physics.. NOT! anyway, can you give me examples of each problems:

1) velocity problems
2) speed problems
3) acceleration problems
4) power problems
5) work problems

please and thank you :)
oh, please be sure that the problems you'll give is the ones that we DO/EXPERIENCE EVERYDAY.

the longer problems but simple answer will have the 10 points :)

If I invent a time machine tomorrow, and the first thing I want to do with it is travel forward in time, will this be possible? Will they be expecting me? Will anything exist if I go forward?

Is it correct to say that an object's mass increases with its speed until it reaches the speed of light, at which point the mass is infinite?

If so, doesn't this mean that the object's gravity also increases?

As it approaches the speed of light, shouldn't the object turn into a black hole? Due to its incredible mass and gravity?

Will the size of the object matter? Perhaps a billiard ball would have to be going at the speed of light to achieve this effect, while a large planet might become a black hole at only 90,000 km/s?

Bonus Question- is my answer to this question okay? http://uk.answers.yahoo.com/question/;_ylt=Aqu4X9dggkkv2l6HRgeBg2kSBgx.?link=answer&.crumb=uHuYKTr5DcP&qid=20070102131855AAGhdnJ&.done=http%253A%252F%252Fuk.answers.yahoo.com%252Fquestion%252Findex%253Fqid%253D20070102131855AAGhdnJ

please give the given, formula, solution & answer. thanks :)

1. A pedestrian is running at his maximum speed of 6.0 m/s to catch a bus stopped by a traffic light. When he is 25 meters away from the bus the light changes and the bus accelerates uniformly at 1.0 m/s2. Find either; how far he has to run to catch the bus, or his frustration distance (closest approach). You may use graphs, charts, appropriate equations, tables, and/or computers.

2. A car, initially traveling with a uniform velocity, accelerates at a rate of 1.0 m/s2 for a period of 12 seconds. If the car traveled 190 m during this 12 second period, what was the velocity of the car when it started to accelerate?

3. A ball is connected to a rope and swung around in uniform circular motion. The tension in the rope is measured at 10 N and the radius of the circle is 1 m. How much work is done in one revolution around the circle?

The Sun’s light takes about 8 minutes to reach Earth after it has been emitted from the Sun’s surface. If God were so gigantic that His feet would be 50 million km long, and only had to take one step to get from the Sun to Earth (a distance roughly about 150 million km), it would only take him less than a second, hence faster than the speed of light, right? If something was faster than the speed of light, would it be invisible, or would it depend on the perspective viewpoint? If there can be things faster than the speed of sound, why can’t there be things faster than the speed of light? On a relative question, if we hear a supersonic jet, does that mean we hear the past?

Note: Since He is God, He can control the universe and therefore He chooses His size and mass will not have any gravitational pull or any other effects on the universe. This is just an example, God may not look anything like a human, or have a body for that matter.

1. A rabbit and a turtle are practicing for their big race. The rabbit covers a 30. m practice course in 5.0 seconds, the turtle covers the same distance in 120 seconds. If the actual race is run on a 96 m course, by how many seconds will the rabbit beat the turtle?

2. A tsunami caused by an earthquake occurring in Alaska in 1946 consisted of several huge waves which were found to travel at the average speed of 790 km/hr. The first of the waves reached Hawaii 4 hours 34 minutes after the earthquake occurred. From this data, calculate how far the origin of the tsunami was from Hawaii.

3. An elevator must lift 1000 kg a distance of 100 m at a velocity of 4 m/s. What is the average power the elevator exerts during this trip?

What are the gravitational effects, if any, of the immense (possibly
infinite) vacuum energy density seemingly predicted by quantum field
theory? Is it really that huge? If so, why doesn't it act like an
enormous cosmological constant?

How comes they defy gravity with their center of mass vertical falling well outside their only support and not falling?
Vector explanations are counter intuitive. I accept them but deep inside something does not convince me completely.
