I assume it is directed 30 degrees above the positive x-axis. F = 50 pounds F_x = 50 cos(30) pounds = 43.3 pounds F_y = 50 sin(30) = 25 pounds Let i and j be unit vectors along the x and y axes, respectively.  Then F = F_x i + F_y j = (43.3 i + 25 j) pounds

The gravitational force between two volleyball players is 3.3x10^-7.
Pepsi [2]

The distance of separation between the two masses is 0.927 m.

<h3>Gravitational force:</h3>

This is the force that exists between two masses in the universe.

To calculate the distance of separation of the masses, we use the formula below.

  • F = GMm/r².............. Equation 1

Where:

  • F = Gravitational force
  • m = First mass
  • M = Second mass
  • G = Universal constant
  • r = distance of seperation.

Make r the subject of the equation.

  • r = √(GMm/F)................... Equation 2

From the question,

Given:

  • F = 3.3×10⁻⁷ N
  • m = 61 kg
  • M = 75 kg
  • G = 6.69×10⁻¹¹ Nm²/kg²

Substitute these values into equation 2

  • r = √(61×75×6.69×10⁻¹¹)/(3.3×10⁻⁷)
  • r = 0.927 m

Hence, The distance of separation between the two masses is 0.927 m
