Avector has an x-component of -7.55m and a y-component of -2.48. find the magnitude of the vector

7.95 meters

Explanation:

The magnitude of a vector can be found with Pythagorean's theorem:

v² = vx² + vy²

v² = (-7.55)² + (-2.48)²

v² = 57.0 + 6.15

v² = 63.15

v = 7.95

The magnitude of the vector is 7.95 meters.

see earlier

  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.
