What is the gravitational force between two runners standing 100 meters apart on a track, if their masses are 60 kg and 75 kg respectively?
F =G•m1•m2/R²
the gravitational constant G =6.67•10⁻¹¹ N•m²/kg²,
Elena, Can you help me on mine? It is the science one. Just go to the list where it says current questions then you will see science then it will say This Girl. That is me. I really need help. I am starting to fail science and my semester is almost up.
Thanks,
This Girl
To calculate the gravitational force between two objects, you need to use the formula for the gravitational force which is given by Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r^2
where:
F is the gravitational force between the two objects,
G is the gravitational constant (approximately 6.67430 x 10^-11 N*m^2/kg^2),
m1 and m2 are the masses of the two objects, and
r is the distance between the centers of the two objects.
In this case, the masses of the two runners are given as 60 kg and 75 kg, and their distance is 100 meters. Plugging these values into the formula, we can calculate the gravitational force between them.
F = (6.67430 x 10^-11 N*m^2/kg^2) * ((60 kg) * (75 kg)) / (100 m)^2
Now let's do the calculation:
F = (6.67430 x 10^-11) * (4500) / 10000
F = 2.251075 x 10^-13 N
Therefore, the gravitational force between the two runners is approximately 2.251075 x 10^-13 Newtons.
