A0.65 lb, 20 inch radius hula hoop is thrown forward with a velocity at the center of gravity of vg = 6 ft/s. however, the hula hoop initially has a backspin of ω = 3 rad/s. if the coefficient of kinetic friction between the hula hoop and the floor is μk = 0.5, determine the time required before the backspin stops. also determine the velocity of the center of gravity at this time. treat the hula hoop as a thin ring.

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
