Before we solve, let's use our formula for speed.
Speed is defined as distance divided by time.
S = D/T
We have 119m and 28s.
Our distance is 119m.
Our time is 28s.
Plug these numbers into the formula.
S = 119/28
Divide 119 by 28 to get our speed.
119/28 = 4.25.
Our speed is 4.25 m/s.
I hope this helps!
Answer:
"we both attract each other with the same force but we know that attraction between two bodies depends upon their mass, greater the mass of two bodies is the force of attraction between them"(got this off the internet).

Answer:
A) Greater than the attraction between two small objects the same distance apart.
Explanation:
The gravitational force between two objects is:
F = GMm / r²
where G is the gravitational constant,
M is the mass of one object,
m is the mass of the other object,
and r is the distance between the objects.
If the distance is the same, then two large objects will have a larger gravitational force between them than two small objects.
Lets use the expression
F = k*x
Where k is the spring constant [N/m]
And x the distance from the equilibrium position.
This force is equal to the force due to the acceleration of gravity
F = k*x = m*g
F = 525[N/m]* 0.30 [m] = 157.5 [N]
157.5 [N] = m *10[m/s**2] ...................> m = 15.75 kg
