Answer:
Explanation:
This problem can be solved with the conservation of the momentum.
If the ball is fired upward, the momentum before and after the ball is fired must conserve. Hence, the speed of the ball is the same that the speed of the car just in the moment in wich the ball is fired.
Hence, the result depends of the acceleration of the car. If the change in the speed is higher than the speed of the ball, it is probably that the ball will be behind the car or it will come back to the car.
If the ball is fired forward, and if the change in the speed of the car is not enogh, the ball will be in front of the car.
HOPE THIS HELPS!!
It takes 3 half-lives:
1. 1000 -> 500
2. 500 -> 250
3. 250 ->125
I'm not sure about the Virginia thing so good luck!
And congratulations on being my first answer-person!!
Gravitational force pushes down on us to keep us on the ground. So it pushes in a downward direction.
