A2000-kg elevator rises from rest in the basement to the fourth floor, a distance of 25 m. as it passes the fourth floor, its speed is 4.7 m/s. there is a constant frictional force of 437n. what is the work done by the lifting mechanism?

a.   mass number from atomic number

radiation

explanation:

heat is transmitted by radiation

  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.
