At a space exploration center, astronauts train on a centrifuge with a radius of 70 feet. a. The centrifuge makes 72 complete revolutions in 2 minutes.
Find the angular velocity of the centrifuge in radians per second.
What distance does an astronaut travel around the center each second?
This is the velocity v of the astronaut.

b. Acceleration is the rate of change of velocity with respect to time.
An object moving at a constant velocity v in circular motion with radius r
has an acceleration of
Using the velocity v from part a. determine the astronaut’s acceleration.

c. One “g” is the acceleration due to gravity on Earth,
about 32 feet per second per second.
How many g’s is the astronaut experiencing in the centrifuge?
How does this compare with a roller coaster?

im not sure

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.

i'm pretty sure the answer is a. decreases with increase in
