Aball starts from rest and accelerates at 0.465 m/s2 while moving down an inclined plane 8.20 m long. when it reaches the bottom, the ball rolls up another plane, where, after moving 16.7 m, it comes to rest. what is the speed of the ball at the bottom of the first plane?

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.
