During an occultation, or "covering up," of Jupiter by the Moon, an astronomer notices that it takes the Moon’s edge 90 seconds to cover Jupiter’s disk completely (starting from the moment of initial "contact"). If the Moon’s motion is assumed to be uniform and the occultation was "central" (that is, center over center), find the angular diameter of Jupiter. Express your answer in arcseconds. [Hint: Assume that Jupiter does not appear to move against the background of stars during this brief 90-second interval. You will need to convert the Moon’s angular speed from degrees per day to arcseconds per second.]

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
