An aerialist is to make a triple somersault during a jump to her partner lasting for the time t = 1.87 s. For the first and last quarter revolution she is in the extended orientation with rotational inertia I1 = 19.9 kgm2 . During the rest of her flight, she is in a tuck position with rotational inertia I2 = 5.50 kgm2 .

a. What must her initial angular speed ω1 be around her centre of mass in order to complete the triple somersault?
b. If she now attempts a quadruple somersault, with the same ω1 and t, by using a tighter tuck, what must her rotational inertia I2 be during the tuck?
c. How long does it take for one rotation in the quadruple somersault?

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
