Ships A and B leave port together. For the next two hours, ship A travels at 20.0 mph in a direction 30.0 degrees west of north while the ship B travels 75.0 degrees east of north at 40.0 mph.

What is the distance between the two ships two hours after they depart?

What is the speed of ship A as seen by ship B?

What is t_a, the time that the arrow spends in the air?

An arrow is shot at an angle of \theta = 45 degrees above the horizontal. The arrow hits a tree a horizontal distance D = 220 m away, at the same height above the ground as it was shot. Use g = 9.8 m/s^2 for the magnitude of the acceleration due to gravity.

What is t_a, the time that the arrow spends in the air?

How long after the arrow was shot should the apple be dropped, in order for the arrow to pierce the apple as the arrow hits the tree?

Does it affect the orbital in any significant manner ?
More than an exact answer an analogy will also do...
If applicable kindly explain the effect of strong, weak or nuclear forces.

The location, movement, time, every measurmeent of every thing and every event, is relative. All will vary based upon the observer, or vantage point. Therefore, calculated speed, inertia, energy, is not a property of a thing itself, but of its relationships to any and all of an infinite number of vantage points, which are themselves relative. This being the case, uncertainty, perceived time, non-local interactions, and the enigmas such subjects seem to create, are all caused by or reinforced by the false idea that we measure "reality", rather than the infinately small aspect involved in any specific view or measurement. Am I the only one who thinks this way? Where am I wrong? Thanks

I possibly had some sort of deja vu, or so.. I've got an instant idea about the origin of time and would like to ask, whats the exact definition of time is today.

ok, despite that it is connected to space and both form what we call spacetime, i'm still not satisfied why it appears to run just forward for us.
how is time defined, and where can one see why its just moving forward ?

I know the basics of refraction but I want to extend my report by adding some interesting things about refraction - eg total internal reflection, rainbows etc. I want to go in much more detail. Any ideas of what I can talk about?
