Generally, the coordinate with positive x-axis and positive y-axis are the basis to resolve the vectors.
The x-component towards right is positive and the x-component towards left is negative.
The y-component vertically upward is positive and the y-component vertically downwards is negative.
Therefore, the set of coordinate axes in third figure are the correct represents to solve the problem.
Which set of coordinate axes is the most convenient to use in this problem?
Draw the most appropriate set of coordinate axes for this
problem (Figure 1 below).
Sketch a set of coordinate axes and plot the given point. Answers:
A rabbit runs across a parking lot on which a set of coordinate axes has, strangely enough, been drawn. The coordinates of the rabbit’s position as a function of time are given by x = -0.31t^2 + 7.2t + 28, y = 0.22t^2 – 9.1t + 30, with x in meters and t in seconds. At t =15 s, what is the rabbit’s position vector in unit vector notation and in magnitude-angle notion?
5. Draw a set of coordinate axes on a piece of graph paper. Label the x axis“Output” (0 to 20 units) and the y axis “Cost” (0 to 20 units). Plot the following (x, y) points on your graph: (0, 4); (2, 6); (4, 7); (7, 8); (9, 9); (11, 11); (13, 14). Connect these points with a smooth curve and label it “Total Cost.” Working from this curve, construct a total fixed cost curve and total variable cost curve...

Choosing the coordinate axes to use is often one of the more difficult choices to make when doing force problems. Almost always the best choice is to choose a coordinate system which is parallel and perpendicular to the net acceleration. For each of the two below situations draw acceleration and FBD diagrams, indicate the direction of the x- and y- axes, and then write the two Newton's law equations. Note: even if the coordinate system rotates you should NEVER...
The electric potential depends on x and y as shown, for the
coordinate axes, in the figure (the potential does not depend on
z). The scale of the vertical axis is set by Vs = 500 V. What is
the direction of the electric field?

17) (10 pts) Draw the FBDs for this problem. Include the choice of coordinate axes and label all the forces. Details count. There is coefficient of kinetic friction of 0.500 between the tabletop and block A. The rope and the pulley are massless and frictionless. Calculate the acceleration of the system using force analysis. Show all of your work. Object A has mass 15-kg and object B has mass 20-kg. MA тв
Identify a convenient coordinate system for analyzing each of the following situationsa. a dog walking along a sidewalkb. an acrobat walking along a high wirec. a submarine submerging at an angle of 30 degrees to the horizontal
this example shows the uses of co-coordinate axes,
my question is why is it that we can substitute T for w2 for
the second equation , won t it be wrong since we are using two
different sets of axes
does it have something to do with expressing newtons second
law in terms of magnittude?
can someone explain more about the uses of co-coordinate axes
and when is it not apprioriate not to use it?
