Abicycle is traveling north at 5.0 m/s. the mass of the wheel, 2.0 kg, is uniformly distributed along the rim, which has a radius of 20 cm. what are the magnitude and direction of the angular momentum of the wheel about its axle?

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
