The initial is where you are starting and the final postion is where the object ends up
Ok so the equation for momentum is:
v=p/m
So you would do:
7800/1200=6.5
So the answer is:
6.5 m/s
Hope this helps :)
When water soaks into the ground fast it means the soil is very moist
<h3><u>Answer;</u></h3>
A. <em><u>
</u></em>
<h3><u>Explanation;</u></h3>
- Using the equation given we can calculate the value of t, time taken by the basket ball to hit the ground.

This question involves the concepts of work done and elastic potential energy.
The work done by the spring when its extension changes from X to X/4 is "0.56 E".
The work done by the spring is equal to the elastic potential energy stored in the spring, which is given as follows:

where,
W = work done = ?
E = elastic potential energy
k = spring constant
X = extension
Now, the spring moves to an extension of X/4, so the change in extension will be:

Hence, the work done will become:

<u>W = 0.56 E</u>
