The answer is approximately 2.998e+8
Answer:
west
Explanation:
The acceleration of an object is equal to the rate of change of velocity of the object, and it is given by:
where
u is the initial velocity
v is the final velocity
t is the time elapsed
For the object in this problem:
u = 65 m/s east is the initial velocity
v = 25 m/s east is the final velocity
t = 10 s is the time elapsed
Substituting, we find the acceleration:
And the negative sign tells that the direction of the acceleration is opposite to the direction of the velocity: so, the acceleration is west.
Answer:
Here you go..

Explanation:
So since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force, so as the mass of either object increases, the force of gravitational attraction between them also increases.
Do both cars leave the starting line at the same time ? That's kind of important. I'll assume that they both start out at the same time, and now I'll proceed to answer the question that I have invented.
-- Car B moves 4 m/s faster than Car A .
-- So Car-A's lead shrinks by 4 meters every second after they start.
-- It takes (10/4) = 2.5 seconds for Car-A's lead to shrink to zero.
-- So Car-B overtakes Car-A <em>2.5 seconds</em> after they start.
