A toy rocket is traveling to the right at 15.0 m/s when it undergoes a constant acceleration 3.00 m/s2 to the left. a. How long does it take before the rocket stops moving to the right?

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.
