Question


Part A

How fast is its center moving?
=
1.30
Correct


Part B

What is the total kinetic energy of the hoop?
=
3.38
Correct


Part C

Find the magnitude of the velocity vector of each of the following points, as viewed by a person at rest on the ground: (i) the highest point on the hoop; (ii) the lowest point on the hoop, (iii) a point on the right side of the hoop, midway between the top and the bottom.

Separate your answers by commas.
=
2.60,0,1.84
Correct


Part D

Find the direction of the velocity vector of each of the following points, as viewed by a person at rest on the ground: (i) the highest point on the hoop; (ii) the lowest point on the hoop, (iii) a point on the right side of the hoop, midway between the top and the bottom.


is directed to the right, = 0 and is directed to the left.

is directed to the left, = 0 and is 45 to the right below the horizontal.

* is directed to the right, = 0 and is 45 to the right below the horizontal.

Correct


Part E

Find the magnitude of the velocity vector for each of the points in part (C), except as viewed by someone moving along with same velocity as the hoop.

Separate your answers by commas.
=
1.30,1.30,1.30
Correct



I need part (F).
Find the direction of the velocity vector for each of the points in part (C), except as viewed by someone moving along with same velocity as the hoop.


vi is directed to the right, vii is directed to the left and viii is directed to the left.


vi is directed to the right, vii is directed to the left and viii is directed to the right.


vi is directed to the right, vii is directed to the left and viii is directed downward.

^^^^^^ which out of those 3 is correct, PLEASE HELP!

Explanation / Answer

c) i    towards right

ii    towards left

iii vertically downward
