Mass = 40.14 - 33.79= 6.35 gram
vol = 13.3 ml
density = m/v = 6.35/13.3 = 0.477 g/ml
Initial inertia = 3.6 kg . m^2
final inertia = 0.80 kg.m^2rotational velocity final = 4.1 rev/s
rotational velocity initial = 0.90 rev/s
lo= lf(final inertia) * Wf(rotational velocity final)/ Wo (rotational velocity initial)
lo = 0.8*4.1 / 0.90 = 3.6 kg m2
Draw a free body diagram to show which forces act in the x and y directions. The x component equation is σfx = 0. The σfx being all the forces acting in the x direction.
Answer:
E means energy
M= Mass
C=speed of light squared (the exponent means squared)
