A box sits on a table. A long arrow labeled F subscript P = 22 N points right. A short arrow labeled F subscript f = ? N points left. A man pushes on the box from the left. The net force acting on the box is 18 N. What is the force of friction?

–22 N
–4 N
4 N
22 N

an energy transformation flow diagram is shown

where is it ?

f=ma newton

f=100x2.5=250n

  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.
