A90.0kg person stands 1.25m from a 60.0kg person sitting on a bench nearby. what is the magnitude of the gravitational force between them ?

Explanation:

According to Newton's law of Gravitation, the force exerted between two bodies of masses and  and separated by a distance  is equal to the product of their masses and inversely proportional to the square of the distance:

(1)

Where:

is the Gravitational Constant

is the mass of the first person

is the mass of the second person

 is the distance between both persons

Solving:

(2)

Finally:

 This is the gravitational force between both persons. As you can see is too small.

it would be kevlar ^^

  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.
