Question

An internal mechanism is used to maintain a constant angular rate Ω = 0.05 rad/s about the z-axis of the spacecraft as the telescopic booms are extended at a constant rate. The length l is varied from essentially zero to 3 m. The maximum acceleration to which the sensitive experiment modules P may be subjected is 0.011 m/s^2. Calculate the velocity of P when the boom in fully extended

1-Calculate the velocity of P when the boom in fully retracted

2-Calculate the acceleration of P when the boom is fully extended

3-Calculate the acceleration of P when the boom is fully retracted

4-The acceleration of point P while the boomer is extending can be calculated with the following equation a_P=Ω ̇×l-Ω^2 l+2Ω×l ̇ Determine the maximum allowable boom extension rate l ̇
