Mary is driving a car of mass 900 kilograms toward the north with a velocity of
22 meters/second. danny is driving his 900–kilogram car with a velocity of
15 meters/second toward the east. they collide and both cars move together afterwards. what is the magnitude of the resultant momentum of the cars after the collision?

= 33,300 Kg m/s

Initial momentum= M1V1 + M2V2

                            = (900× 22)+ (900 × 15)

                            = 33,300 Kg m/s

Since; initial momentum = final momentum

Final momentum or the resultant momentum = 33,300 Kg 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.
