Q. No. 3 A parachutist of total weight 950 N falls vertically at a constant velocity of 6.5
m/s.
(a) State the size and direction of the resistive (drag) force acting on the
parachutist

-size of resistive force:

-direction of resistive force:

(b) At a certain height, the wind starts to blow and the parachutist moves
horizontally at a velocity of 4.5 m/s as he continues to fall. Use a graphical
method to add together the horizontal and the vertical velocities to determine the
size of the resultant velocity of the parachutist. Label the velocities and state the
scale that you use.

c, 1a 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.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
