An old truck compresses a spring scale at the junkyard by 25 cm. the spring constant for the industrial scale at the junkyard is 39,200 n/m. what is the force applied to the scale by the car?

ill do it for 100, also this isnt 80 its 40

probably not if net force is zero

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

  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.
