Because the mouth breaks down the food and the stomach uses acid to break food down even more
Answer:
-5m/s²
Explanation:
Given parameters:
Initial velocity = 25m/s
Time = 5s
Final velocity = 0m/s
Unknown:
Acceleration of the car = ?
Solution
The acceleration of a body is the rate of change of the velocity of the body with time.
Acceleration =
So;
Acceleration = = -5m/s²
The car is decelerating at a rate of 5m/s²
My guess would be because the gravity from the Earth's core is constantly pulling the ball towards the ground. It's like the moon. Why doesn't the moon just float away in space? Because Earth's gravitational pull keeps it rotating around it. Therefore, the ball will always be pulled towards the core which keeps it from from rolling forever due to friction. But i may be wrong, even though this a quite a good answer, hope it is right!
They all have the same aphelion distances
