Compute your average velocity in the following two cases: (a) You walk 90.0 m at a speed of 1.06 m/s and then run 90.0 m at a speed of 3.47 m/s along a straight track. (b) You walk for 1.00 min at a speed of 1.06 m/s and then run for 1.41 min at 3.47 m/s along a straight track.

If a person jumps from a building and maintains a verticle position with arms at the side how far would they have fallen after 3 seconds? 5? 8? Conversely, how fast would you be going when you hit the ground after jumping from a 5 story building? 10 story? and how long would those last two trips take?

Assuming it was possible to reach the speed of light, how long would it take to accelerate to 186,000 miles per second at the rate of acceleration that a human being could withstand for that period of time?

As we know there are supposed to be 11 dimensions in this world.... we humans can only see and feel 3 of them!
i have a doubt whether things like ghosts live in a higher dimension?
they are right next to us but we just cant see them!

what u think.....

surely if it reflects off something it must be tangible, which means if there were enough of it its could force things to move.... i know we could never have enough light to do that, but is the theory true?

Just need an awnser, i think i got this wrong on the test, but if you would like to explain, your more than welcome.

A Plane travels due north at 200 km/h
The plane is being affected by wind traveling 50 km/h from west to east. How fast is the plane going relavtive to the ground. I said about 219. Thanx

Project Criteria: The size of a shoe box. ~The protection for the egg must be engineered, not just filled with stuff.~No type of packing material will be allowed. This includes but may not be limited to such items as : bubble wrap, cotton balls, tissue , styrofoam pellets, cronstarch pellets, pillows, stuffed animals, shaving cream, paper, ballons or egg crate foam. No type of food may be used as packing material. This includes : jello, marshmallow, popcorn, or peanut butter,~ No wooden or metal boxes~No parachutes or helium filled balloons will be allowed~The egg will be provided at the time of the drop which you will then have to insert it into your project~ No boxes will be accepted that are preloaded with an egg. And it must have physics behind the design. Including Newtons laws of motion, terminal velocity, momentum, and gravity.

Thanks for the help ahead of time.

Trying to do this homework question, but cant figure it out, can any one help please????

You have a lightweight spring whose unstretched length is 4.0 cm. You're curious to see if you can use this spring to measure charge. First, you attach one end of the spring to the ceiling and hang a 1.0 g mass from it. This stretches the spring to a length of 5.0 cm. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.5 cm.
