Answer:
READ THIS FIRST!!!
I am not going to right the parragraph (it says to use your own words, they could trace it back to me if you use my words, and you would get it trouble).
But I will tell you the forces acting on the pencil:
Gravity (pulls on the pencil)
Your hand (pushing it up canceling out gravity)
And the electromagnetic force (holding the thing together)
Hope it helped,
Have a good day
Answer: a. ) What is the magnitude of their average acceleration (in m/s2)
Incomplete question. However, I provided a brief about Kinetic energy generation.
<u>Explanation:</u>
Interestingly, Kinetic energy in simple terms refers to the energy possessed by a body in motion.
It is often calculated using the formula E =
A good example of creating even more kinetic energy is a hand crank toy car that moves after you wind it a little, when the car moves it is generating another measure of K.E.
It can be noted that the directions west and north are perpendicular to each other. hence we can use the right angle formula for calculating total distance in these directions. Also South is just negative north. This technique is called euclidean distance norm. It is the basis of Cartesian coordinate system.
Total distance = 3.22 N + 4.75 W +1.90 S
= 1.32 N + 4.75 W
D = 
D = 4.93 Km
direction = atan(N/W) = 15.53 deg north of west
