The first thing you do is go two space forward like start at the o and move two spaces forward you put a decimal at 9 like this 0.90 and that's how you do it
KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
The rope is not long enough a meter is roughly 3 feet 3 inches totalling out to 98 feet and a few inches
The answer would be 40
5 divided by 1/8
5/1 divided by 1/8
5/1 divided by 8/1
then you would multiply
5 times 8
=40/1 or 40
If he got a 23 out of 25 just divide 23 by 25 and your answer would be
Answer-92%
