A model rocket is launched straight upward with an initial speed of 40.0 m/s. It accelerates with a constant upward acceleration of 1.00 m/s2 until its engines stop at an altitude of 170 m.
a) What is the maximum height reached by the rocket?
(b) How long after lift-off does the rocket reach its maximum height?
(c) How long is the rocket in the air?

My friend and I built a 2-stage model rocket using estes engines. The C-6-0 is on bottom and the C-6-7 is stacked about one inch above the other. We are relying on the charge from the C-6-0 that normally sets the parachute off to ignite the C-6-7 just above it. Will it work????? any thoughts??

I have never been on a cruise before. I am going on a cruise in March to Mexico, Belize, and Grand Cayman on Royal Caribbean. I was wondering if anyone who has been on a RC cruise could give me an estimated price range for cocktails, and other alcoholic beverages on the ship.
Also… Am I allowed to purchase a bottle of liquor in one of our destinations, and bring it back on the boat with me to my room?
please and thank you

Casual talk with a stranger lead to him suggesting me getting Flowmasters on my Tacoma. Did a search on Youtube and a Tacoma with Flowmasters sounded like a rice rocket. Can someone confirm this to be true/false? Or does it sound like a traditional muscle car/truck?
What is the suggested Flowmaster model kit to use, and what is the pricing for installation+kit?
Are there any benefits for this new exhaust system (i.e. improved gas mileage, pwr)? Or is it all for looks?
Your help would be great!

While most of us think of putting gifts under the tree, how many of you have seen people put a model train running under the tree? Or have you done it yourself?
I see ones that have a large-scale LGB toy train running in a circle under the tree. My own tree, I’ve used HO scale, which is much smaller, and allows room for buildings and scenery.
How ’bout you?
And, Merry Christmas!

Well first off, ill start by saying that i already have abs and you can see the ’6-pack’ as i also have little fat. However, i wanna bring it up to the next level, yknow, the type you’d see on underwear box models ?
First off, will crunches do this for me ? Whats a good # of rep ? I get sorta pissed being able to do so many. All these while ive been doing tons of sit ups, but i hear crunches are more effective. So i tried it, but i felt like some turtle on its back, and strained my neck too.
Secondly, they say it only trains the upper abs ? Definitely i wanna train the whole thing so info is much appreciated!
Um..i have no fat problem, i just need to build it up

Ok, so I am some what of a geek, I like to pick a project of some sort and work to get it to work. I want to get a camera to wirelessly send video to either my computer or my TV. So my question is, Is their any commercial product I can get, or am I going to have to modify something? I am going to connect this to an RC car for air-soft battles. I might even put the camera on an RC heli. that would be cool. Anyways, thanks!
