Anovice golfer on the green takes three strokes to sink the ball. the successive displacements of the ball are: - 4.0 m north - 2.0 m northeast - 1.0 m at 30◦ to the west of south starting at the same initial point, an expert golfer could make the hole in what single displacement?

its displacement is given in vector form as follows

now the total displacement due to all three is given as

so magnitude of displacement is

direction is given as

so the ball will be displaced by 4.63 m at angle 78.7 degree North of East

  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.

it is a negative acceleration
