The moon has a mass of 7.35 e 22 kg and is located 3.84 e 8 meters from the earth. if ellen, an earthling, has a mass of 47 kg, what is the gravitational force between ellen and the moon?

The gragitacional force is 1.56 10⁻³ Kg

Explanation:

The gravitational force between two bodies is proportional to their mass and inversely proportional to the square of the distance between them, is described by the equation

      F = G m₁ m₂ / r²

With G being the universal gravitation constant with a value of 6.67 10⁻¹¹ Nm²/Kg², as they give us the mass of the bodies and the distance between them, we can calculate the force.

     F = 6.67 10⁻¹¹ 47  7.35 10²² / (3.84 10⁸)²

     F =  1.56 10⁻³ Kg

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
