Answer 3

D I am sure because the graph shows an acceleration of (2.5, 14) which is positive and also as you can see it is increasing

Answer 4

@MD152727 I would agree. But instead of giving the answer, you should help the user find it themselves.

Answer 18

the gravitational force between two objects with masses \(m_1,m_2\) is given by
\[F = G\frac{m_1 m_2}{r^2}\]where \(G\) is a constant and \(r\) is the distance between the centers of mass of each object.

You do not need to know the value of \(G,r, m_1\) to figure out this problem. The value of \(m_2\) will be the mass of the object you are considering. How will the value of \(F\) vary as \(m_2\) varies?
