P10.15)fe A 1200-kg! satellite is inserted into its orbit with its solar panels collapsed rotating about its z-axis at a rate of 1.5 rev/sec. Determine the satellite's angular velocity after its solar panels deploy. You may assume that the satellite has a radius of gyration with respect to the P10.1-5 ect to the mass center about the z-axis of 0.5 m when its solar panels are collapsed nd a radius of gyration of 0.85 m when its solar panels are deployed. and a r d) = 0.82 rev/s c) = 0.72 revs II SF-MOMENTUM PROBLEMS () = 0.52 rev/s b) = 0.62 rev/s

Explanation / Answer

Angular momentum conservation

I1w1 = I2w2

m*Rd1^2 * w1 = m*Rd2^2 * w2

Rd =Radius of gyration

0.5^2 * 1.5 = 0.85^2 * w2

w2 = 0.52 rev/sec

Answer is option a
