Answer:

Understanding projections and coordinate systems important knowledge to have, especially if you deal with many different sets of data that come from different sources. Projections Distortion Coordinate Systems Datums

A Cartesian coordinate system. Locations on the Earth's surface are measured and represented in terms of coordinates; a coordinate is a set of two or more numbers that specifies the position of a point, line, or other geometric figure in relation to some reference system.

• Check Layer Properties > Source > Spatial Reference to find out what coordinate system your data is in. If it says “Unknown Coordinate System” you definitely want to use the Define Projection tool. • The Define Projection tool will not make a copy of your data.

Math coordinates identify the location of a point on a graph or map. The ordered pair, (x,y) is the address of the point. The Cartesian coordinate system is the graph used to locate the point.

You throw a rock upwards; it rises and then falls back down. We know that the acceleration due to gravity is 9.8 m/sec2 near the

Leokris [45]

Answer:

Acceleration = 9.8 m/sec2

Explanation:

We know that the acceleration due to gravity is 9.8 m/sec2 near the surface of earth.

Remember that the gravity is always affecting everything on earth at every instant, even the rock at the very top of it's trajectory. It doesn't mind if the velocity is zero for an instant or if there's air resistance, the gravity force is there, and always aims towards the center of the earth.

So for all the trajectory of the rock, gravity is 9.8 m/sec2

A 1.2-kg mass is projected from ground level with a velocity of 30 m/s at some unknown angle above the horizontal. A short time

Dmitriy789 [7]

Answer:

$K_f$ = 351.84 J

Explanation:

Using the conservation of energy K:

$E_i = E_f$

so:

$\frac{1}{2}mv^2 = K_f + mgh$

where m is the mass, v the initial velocity, $K_f$ is the kinetic energy of the mass as it clears the fence, g the gravity and h the altitude.

Then, replacing values, we get:

$\frac{1}{2}(1.2kg)(30m/s)^2 = K_f + (1.2kg)(9.8m/s^2)(16m)$

solving for $K_f$ :

$K_f$ = 351.84 J
