You want to use a rope to pull a 109kg box up a plane inclined 30° above the horizontal. the coefficient of kinetic friction is 0.42. if the rope pulls parallel to the incline, what force do you need to exert on the rope to pull the box at a constant velocity?

c)as speed changes, wavelength and frequency change.

everything changes!

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

  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.
