As you go west of Greenwich you go earlier and as you go east you go later.

Can an object have an eastward velocity while experiencing a westward accelerations?
The answer is yes and no.Acceleration is the rate of change of velocity. Velocity is speed plus direction.If an object is travelling eastward and slowing down in a straight line then its velocity is decreasing, it is still travelling eastward. However the force slowing the object is a westward force.A reducing acceleration (slowing down) is most often called a deceleration or negative acceleration. So you have a negative eastward acceleration.
What force acting for 0.025 seconds will change the velocity of a 100 gram baseball from 35 ms eastward to 20 ms westward?
use the Impulse-Momentum theorem where (Fnewtons)(tseconds)=change in momentum change in momentum=Pf-Pi; P=mv
When it's noon at Greenwich England what time is it where the Prime meridian crosses the Arctic Circle?
For the most part, time zones don't change north to south. It would still be noon.
What is the meaning of greenwich mean time?
Greenwich Mean Time (GMT) is the time of day at any point on the Greenwich meridian (the zero degree line of longitude). It is from this time that all other time zones on earth (+ or -) are compared therefore if you want to communicate things that happen all round the earth you use GMT to communicate this (rather than your local time) to avoid confusion and the need for calculations.
If the international date line can be shifted why not the Greenwich meridian?
Because the result would be anarchy!Sailors, airplane pilots, military ground forces and general civilians use Greenwich as the reference point of zero degrees longitude for all navigaton purposes. Repeat: ALL navigation purposes. Charts created a hundred years ago and still in use today refer to Greenwich as point zero. Time almanacs for celestial navigation (using a sextant or computer programs and/or in electronic charts) are in print, or computerized, or even in some cases memorized, that allow people to calculate their position upon this planet using Greenwich as the reference point.GPS systems in automobiles, upon ships & planes, in hand-held devices, would all have to be recalibrated should the reference point be changed.While yes, it is technically possible to change the Prime Meridian, there is no -- repeat NO -- advantage to doing so. Conversely, there is a HUGE monetary and technilogical cost to changing from the status-quo. Like it or not, Greenwich is, and will remain, the Prime Meridian.
How did moving westward change settlers lives?
something big

Because of their constant westward migration.
How did mining and cattle ranching change during Westward Expansion?
good
If a car is traveling westward with a constant velocity of 20 meters per second what is the net force acting on the car?
well as we know that velocity is a vector hence it has magnitude as well as direction. Let us assign sign conventions for direction of velocities in this example: Let eastward velocity be positive and westward be taken as negative. Initial Velocity:-20 Final Velocity:+5 CHange in velocity=Final velocity-Initial Valocity Change in Velocity=5-(-20)=25m/s So change in velocity will be 25m/s
