Two force vectors are perpendicular, that is, the angle between their directions is ninety degrees and they have the same magnitude. if their magnitudes are 655 newtons, then what is the magnitude of their sum?

Explanation:

To calculate the magnitude of the sum of the vectors we must find their components on the x and y axes, in this case, since they are perpendicular, one vector is on the x axis and the other is on the y axis:

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
