Collar p slides outward at a constant relative speed along rod ab, which rotates counterclockwise with a constant angular velocity of 3.65 rad/s. knowing r = 14.34 in when theta = 0, and the collar reaches b when theta = 98 degrees, determine the magnitude of the acceleration of the collar p just as it reaches b in ft/s^2.

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.
