The centripetal acceleration of an object is given by the relation,
where Ac = centripetal acceleration =
R = radius of rotation = 15 m
V = speed of astronaut
Hence,
solving this we get, V = 38.34 m/s

Answer:
A
Explanation:
hope it helped a lot
pls mark brainliest with due respect .
Answer:
Option B
Explanation:
Given information
Radius of container, r=12cm=12/100=0.12m
Angular velocity= 2 rev/s, converted to rad/s we multiply by 2π
Angular velocity,
We know that speed,
Centripetal acceleration, and substituting
we obtain that
Substituting \omega for 12.56637061 and r for 0.12
Rounded off,
Equation C describes the sum of the vectors plotted below.
<h3>What is a vector?</h3>A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.
If no vector can be written as a linear combination of the others, a set of vectors is said to be linearly independent.
The given points from the graph is obtained as;
a = (2,1)
b = (3,-2)
Vector, OA = 2x + y
Vector, AB = x - 3 y
From the triangular lawe of the vector addition;
Hence,option C is correct.
