okay, I've uploaded a diagram so should the force off the wall equal the frictioanl force in equilubrium ?

okay so first i have to find the components that will make all the forces acting on the ladder perpendicular. I will choose the very bottom of the ladder as my pivot point therefore eliminating the normal force from the ground and the frictional force on the ladder. because when R= 0, torque =...

Homework Statement Mr. X ( mass 96.0 kg ), he just finished a rather large breakfast) is finally getting around to taking down his holiday lights when a sudden ice storm hits. the coefficient of static friction between his ladder (mass 16.4 kg ) and the level ground has been reduced to 0.090...

so if v1 = 10 m/s , think wut would the speed be at maximum height , and remember there is always the acceleration of gravity [ down ] acting on all object thrown upward!

To answer the mirror question, well no MIRROR is 100% reflective, so some heat will be absorbed, the only way i can think of is : To use a mirror with a material so the particles aren't close enough to trap the heat and allow the heat to dissipate away from the reflecting surface, and out the...

redargon and Danger ! This is an excellent point you have pointed out ! Newton's third law, which I have avoided using because in space it causes a headache according to it, The ISS would have to exert an equal force at the "back" and that should solve the problem, so there will need to be a...

This idea you propose might work, but as you know things left in orbit go around the planet and orbit , so the beam will not be constantly reflected back, this mirror or reflective surface will need its own fuel to maintain its position between the planet and the vehicle! Correct me if I'm wrong !

not a bad idea at all, i know quite a bit about solar sails but its still within the grasps of SF, redargon Thank you for pointing out the obvious flaw of flying back, i had not thought of it! And for this idea to work i was thinking STRICTLY launched from space. 1. Vehicle is...

Therefore less fuel is used to accelerate the vehicle because of a smaller mass, however, just how far can this laser propel it, are there any technologies (laser) that for example can be based on Earth or the ISS and "push" it possibly to the moon, or from the moon to mars. I am aware that once...

LURCH - that might just work, in searching for an alternative source of propulsion, because of the rising price of fuels, air would be very cheap. Another method would be , correct me if I'm wrong, is to use somesort of reflective surface on the craft and shine the laser on that, more complex...

Thank you very much ! All i wanted to know and more ! :)

Thank you for that quick answer, that's exactly what i was looking for , is if there is a fuel that can potentially use the power of a laser to ignite! I guess I'm back to the drawing board!

or is this idea of igniting fuel using a laser too sci-fi?

Is it possible to detonate or to ignite a fuel and air mixture using lasers, or a laser pulse, any type of laser, CO2 or other wise ? or is there any possible way of using Lasers for the propulsion of an aircraft, i am already aware of several methods, but they do not include ignite fuel, any...
