The Mass of the barter and the ball is 3.1kg
Data Given;
- F = 1.1*10^-9N
- r = 0.76m
- G = 6.67*10^-11 m^3 kg^-1 s^-1
Assuming the barter and the ball have equal mass, we can apply gravitational force formula.
<h3>Gravitational Force</h3>
This is product of the mass of the two bodies and divided by the square of their distance apart.
Substituting the values into the formula
From the calculations above, the mass of the barter and the ball is 3.1kg

Yes everything is made of cells because without cells our being can't stay together.
Answer:
The final velocity of the object is 330 m/s.
Explanation:
To solve this problem, we first must find the acceleration of the object. We can do this using Newton's Second Law, given by the following equation:
F = ma
If we plug in the values that we are given in the problem, we get:
42 = 7 (a)
To solve for a, we simply divide both sides of the equation by 7.
42/7 = 7a/7
a = 6 m/s^2
Next, we should write out all of the information we have and what we are looking for.
a = 6 m/s^2
v1 = 0 m/s
t = 55 s
v2 = ?
We can use a kinematic equation to solve this problem. We should use:
v2 = v1 + at
If we plug in the values listed above, we should get:
v2 = 0 + (6)(55)
Next, we should solve the problem by performing the multiplication on the right side of the equation.
v2 = 330 m/s
Therefore, the final velocity reached by the object is 330 m/s.
Hope this helps!
