In the movie "star War's. there are mamny scenes showing spacecraft proplsion. Researchers have not yet gotten the Faser-Than-Light hyperdrive to work. Can you explain why this is true using newton's three laws?

I agree that newtons laws do not apply to hyperdrive. But, can you explain why newtons laws say that hyperdrice can NOT work.
This is a homework quetsion..and i have to explain with Newton's 3 Laws. And i am copletely stumped...

This is beyond classical physics, which is Newton's Laws. Newton's laws apply at well-below sublight speeds. At speeds approaching light, Einsteins theories take over. Researchers have not traveled faster than light because Einstein proved that it is not possible. Don't confuse fantasy with reality.
However, as you approach the speed there is a distortion of space (you lengthen in the direction of the travel), and time (time slows as you approach the speed of light). The latter has been proven as accurate clocks on spacecraft return to earth to be found running slower that a comparitive clock on earth.

The movies do not really say what hyperdrive is, but we can suppose it is REALLY fast. Newton's laws do not say anything about not being able to go really fast, even faster than light, like Einstein does. Ignoring Einstein and using Newtons laws at all speeds, we can proceed. Newton's second law says that to change your speed, you need to accelerate by using a force. To get up to the speed of light at 1G of acceleration would take a very long time, about a year, not a second or two like it does in the movie. If you were to go from zero speed to the speed of light in one second, it would be much worse than being shot out of a gun. The millions of Gees acceleration would smash you to jelly!

Hyperdrive is a myth, Warp drive however is the real deal. Newton's laws of motion only hold up for low accelerations. Acceleration and gravity are equivelent according to General Relativity. In General Relativity, a large mass can warp space. Also, energy and mass are equivelent E=MC^2. This means if you have enough energy, you can warp space making the distance you have to travel to a destination shorter. This means you get there faster.

Newton's laws do not apply to hyperdive (faster than light travel).
