The acceleration experienced by the particle is given by
This corresponds to the centripetal acceleration of the motion, which is related to the angular speed
of the particle and its distance r from the axis by the relationship
In our problem,
, so we can solve for
:
However, we must convert it into rpm (revolution per minute).
We know that 1 rad corresponds to
revolutions, while
. So we the conversion is
The solution for this problem is:
m = k*(T/2pi)^2
<span>mass of chair is computed by: 606*(0.889/2pi)^2 = 12.13 kg </span>
<span>mass of chair + astronaut is computed by: 606*(2.15/2pi)^2 = 70.96 kg </span>
<span>so mass of astronaut is now 70.96 - 12.13 kg = 58.8 kg (3 s.f.)</span>

I think its true, I think.
Answer:
<h3>Newton's 2nd law states acceleration is proportional to the net force acting on an object. The net force is the vector sum of all the forces applied to the object. ... In this case the acceleration (slowing down) of the puck is proportional to the amount of friction.</h3>
