Answer:
Velocity is a function of time and defined by both a magnitude and a direction. [1] Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity. Using the information given in a problem, you can determine the proper equation to use and easily answer your question.
This is from a website btw.
Answer:
Yes, because of both gravity and the fact that nothing is obstructing the hole.
Kinetic energy since if its rolling is already using the stored potential energy that it had before it was given an amount of energy to release it for a given time
Answer:
20N
Explanation:
Ratio of N to cm-
10:2
so to make 2=4 times 2 so The ratio is now-
20:4
so to move 4 cm you need to push 20N.
Answer:
We only see one side of the moon due to the synchronous rotations and the earth rotation ration is approximately 27 days
