The point is it impossible as the mass is too high & there is no slope...:P
@Ibanez .......E = mc^2.....speed will have to be increased so high that the mass seems to be negligible.....Maybe equal to that of the bullet itself or mayb even lower......:P

@sid2222000 said:@Ibanez .......E = mc^2.....speed will have to be increased so high that the mass seems to be negligible.....
But E=mc^2 is the equation of the enery when mass m is destroyed. how will we use that here?
@Ibanez said:Lekin the motion should be horizontal here. Not a trajectory. Even if it is, it's curve should be neglegible. A bullet won't follow a trajectory for example..
Dekho.. eee projectile motion ka Prashn hai.. Jisme Horizontal motion keval 1 Point pe hota hai.. i.e. The Highest Point! In your case, even if we consider this distance 'd' to be a point, then Radius of curvature Infinite ho jaega! and 
Horizontal Motion nhi hoga.. coz uspe keval Gravitational force lag rha hai.. No counter force in upward direction except for Air Buoyancy.. which is very less to counter Gravity! Hence the Paradox!

@Ibanez ....See the point is as a body travels it becomes lighter till its speed reaches the speed of light when its mass will become zero......so if its speed it high enuf then the force with which it is pulled down will become lower (F=mg) & hence it will be able to fly...so high....:P

Then how does a bullet travel? Bullet shuru se hi projectile motion kaise kar sakta hai. Only after a certain distance it does.

I didn't use it bhai. @sid2222000 sir had said something about it so I was asking :)

But if we assume it's speed to be equivalent to that of light then there will be time dilation and the equations of motions will no longeer be valid in that case. But a bullet can travel horizaontally upto a certain distance and hit it's target without deviating from it's path. How then?
@Ibanez .....It is not destroyed....it changes in2 another energy form.....ab ye mat puchna ki konsa waala...:P

Bhai ek kaam kar...partal lok mein jaa...wahan Einstein ...Newton....etc ke bhoot ghum rahe honge...unse solve karva la...

But we shouldn't necessarily need the speed of light . I mean how does a bullet hit it's target? which is perfectly horizontal and at a great distance. Guns like HkPK-12 have a laser pointer and it hits exactly at the target. Ye kaise hota hai?
@Ibanez @sid2222000
bhai log cat aa raha hai... board k exam nai... iska discussion Feb me karenge.... :P
@Ibanez .......Its because its speed is high enough & its mass is very low & hnce a very high momentum & low force pulling it down.....& it eventually goes down....one more thing imagine someone pulling the trigger & giving u a smack on the back.....as the mass is 10000 times more so the speed also has to increase proportionally....also no friction is thr in case of bullet whereas in case of car there is....which makes it even tufer to reach that speed(keeping in mind the proportionality....:P )

But bullet mei friction hota toh hai. Air resistance. The mass of a bullet is let's say x kg. and it's speed be y m/s. so the ratio x/y is constant then it should be valid for the car as wel? Only the mass x will increase but y can also increase proportionally. So it shouldn't be as large as the velocity of light?
@Ibanez ......Shape matter krta hai bullet ke case mei kyunki Air friction hota hai aur bullet is streamlined shaped which helps reduce air friction.......haan speed of light nhi bol rha mai....but imagine a speed 1000 times that of the bullet......is it achievable...??:P
@Ibanez said:Guys one Physics conceptual question.Suppose this is a broken bridge A=======B-----------------------C=======DWhere -------- denotes the broken part (i.e. BC) Assume ABCD to be perfectly straight.Let the distance BC be d units.Assume AB and CD to be any length as per convenience.A car starts from A and it can only traverse horizontally. What should be the minimum speed of car (in units/sec) so that it can just cross the bridge BC. (meaning it's motion should be perfectly horizontal for the distance BC ).
Its possible wen u apply the principle of launching a satellite in this....see acc to conventional theory....an object needs to be between 17000mph-23500mph speed to counter the of gravity.....
Here hence speed of car should be min as- 17000*60*60 m/sec for 1 m....
Tell if m right....:P
