Answer: Newtons second law of motion: the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.
Explanation:
Hope this helps you! Have a good day!
Answer:
A.)
Explanation:
Because you didn't add anything or take anything away.
Vector quantities are always defined by magnitude and its direction.
Here, to define number of coins in a piggy bank, we don't need direction. Hence it is a scalar quantity.
I believe the answer to that question is A. If you can obtain the time it takes to reach the bottom of the cliff, then you can solve for the other two values.
