What is the acceleration due to gravity at 49 degrees north latitude?

The acceleration due to gravity is not a constant across the face of the earth, as is astutely suggested from the nature of the question. The acceleration due to gravity on earth is given by g , and it is about 9.789 m/sec2 at the equator and about 9.823 m/sec2 at the poles. The observer might conclude with a bit of thought that the effect of gravity at the poles is a bit higher because of the shape of the earth, which is sometimes termed an oblate spheroid by astrophysicists. The earth is flattened up top and down bottom, and is a bit "fatter" in the middle. That means that a body on the equator is farther from the effective center of pull of gravity of earth. It will weigh less on the equator. And more on the poles where gravity is higher. At 49 degrees north latitude, the value of g is some 9.8707 m/sec2 there. Note that the general value often given for g is some 9.8 m/sec2, and it is applied for much work in "regular" mechanics.

What is the magic number for acceleration due to gravity?
It varies depending on your latitude with the equator having a slightly higher acc. due to gravity than the north/south pole . 9.8 m/s^2 is the average for the earth
What is the value of acceleration due to gravity g in Dublin Ireland?
The acceleration of gravity (9.80 meters per second squared) does vary a bit with latitude because of the effects of centripetal acceleration as well as differences in the Earth's polar and equatorial diameters.1 But the variance isn't noticeable until the third significant figure. The acceleration due to gravity will be somewhat less in Dublin than at the equator because Dublin's latitude is 53 degrees, 20 minutes North Latitude, closer to the pole than the equator. To calculate a more precise value (more precise than just 9.80 m/s2) would require you to know the radius of the Earth at your location, since g = GMe/Re, where G is the universal gravitation constant, Me is the mass of the Earth, and Re is the radius of the Earth. From that you would substract the centripetal acceleration, which can also be calculated based upon your latitude. (Which is an answer to another question that hasn't been asked yet!) _________ 1. The Earth is not a perfect sphere. The equatorial diameter is greater than the polar diameter. Hence, g will be slightly greater at the poles than at the equator. And because the Earth rotates, the acceleration of gravity will be reduced by the centripetal acceleration, which is greatest at the equator. So, if oyu want to lose weight, move from Dublin to Ecuador.
When is acceleration due to gravity positive and when is it negative?
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
Direction of an object's velocity changes uniformly frome east to north What is the direction of acceleration?
North-west. More specifically, as the object's velocity direction changes uniformly from east to north, the acceleration and force producing this acceleration are both constant and changing direction uniformly from north to west.
What are not vector directions?
north, 35 degrees north of east
