Answer:
It is positive and smaller in magnitude than the initial acceleration.
Explanation:
We know that acceleration is defined as the change of velocity in a given time.
We see that the time interval is equal to 30 seconds (70 - 40). In this interval we also see that the velocity increases from 245 to 250 (m/s) approximately. Therefore the acceleration is positive.
With respect to the magnitude we can say that it is smaller than at the beginning since the change of velocities is smaller with respect to the change of velocities at the beginning.
The compound is an indicator
Answer is Weaker. If it is talking about the objects' gravitational forces.
<span>The condition alone that is necessary so that the final kinetic energy of the system is zero after the collision is that the
objects must have momenta with the same magnitude but opposite directions.</span>
Force that is of equal magnitude
