Answer:
Option A: a_c = a_t
Explanation:
Let's denote the force acting on the car due to the truck as F_ct
Similarly, the force acting on the truck due to the car is denoted as F_tc.
Now, F_ct = m_c × a_c
Where;
m_c is mass of car
a_c is acceleration of car
Also, F_tc = m_t × a_t
Where;
m_c is mass of truck
a_c is acceleration of truck
Now, since the car is the one pushing the truck, from Newton's laws, we can say that they stick together and move in the same direction at the same acceleration.
Thus, the truck will move with an acceleration equal to that of the car pushing it.
Thus; a_c = a_t
Gravitational force = Gxm1xm2 /r^2
This equation depends only upon object's masses and distance between them. So option b is correct
Answer:
