An object weighing 10 grams is spinning in a centrifuge such that an acceleration of 13.0 g is imposed to it. the arm connecting the shaft to the object is r = 6.0 inches. if a = acceleration = rω2 where ω = angular speed in rad/s, determine:
mass of the object in lbm
rpm (revolutions per minute) of the shaft
force acting on the object in lbf

1) 0.022 lbm

2) 276.253 RPM

3) 0.287 lbf

Explanation:

Given data:

mass = 10 kg

acceleration -

7.53 m/s^2

r =6 inches = 0.1524 m

1) mass in lbm  

as 1 kg = 2.2 lbm

2) acceleration

SO IN

3) Force in

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

b.

the accuracy of the data.
