if you are traveling at the speed of light and you looked in a mirror you would not see your reflection , correct?

Why can't there be an artificial way to manipulate the speed of light? Why does it have to be exactly 186000 miles/sec?

A car accelerates uniformly from rest and covers a distance of 65 m in 5.7s. If the diameter of the wheel is 40cm.
1. Find angular acceleration of the wheel. Answer in rad/s^2
2. Find the final angular velocity of one of the car's wheels. Answer in rad/s.
3. Find total number of rotation of the wheel.

I left my book at school, and i dont have any of the formulas to help me. Any help would be greatly appreciated. Thank you in advance.

Estimate the force a person must exert on a string attached to a 0.200 kg ball to make the ball revolve in a horizontal circle of radious 0.600 m. The ball makes 1.00 revolutions per second. Do not ignore the weight of the ball. In particular, find the magnitude of FT, and the angle it makes with the horizontal. [Hint: Set the horizontal component of FT equal to maR; also, since there is no vertical motion, what can you say about the vertical component of FT?]

I have solved this question and got the answers 4.74 or 4.76, both or which are wrong. I can't seem to find an error in my solution, but if you can please inform me. Thanks

they say its impossible to travel through time, no matter how advanced technology is. Why?

Is this right?

For this example I will use a rectangular wood block. It is slid on a piece of wood. It is then turned on it's side (less SA) and once again slid on the piece of wood.

The Static (Initial) friction will be equal no matter what the surface area of the wood. So in both cases the static friction should be the same?

For kinetic friction it should also be equal in both cases?

Please confirm if this is right or wrong, it is the kinetic friction I am a bit confused about right now. Any help is much appreciated.

if we have 200, four-hundred pound men... sitting in a large bus, traveling at 176 miles per hour... what is the average speed of this bus if one of these men roasts a frankfurter.... thus slowing the bus to 136 miles per hour for 5 minutes..??

what is the average speed of this bus over a 50 mile course????

if we have 75, four-hundred pound men, sitting in a bus which is traveling at 168 miles per hour down the hi-way.... what is the average speed of this bus, if after 20 miles, these large men begin yodeling, pissing off the bus driver, thus slowing the bus to 98 miles per hour for 3 minutes...
during this time, the bus driver will tell these large yodelers to cease their yodeling... then the bus driver will increase the speed of the bus back to the original 168 miles per hour... so what is the average speed of this bus after 60 minutes???
