5) A car accelerates with a force of 12,000 N and experiences 1,000 N of friction. The car is pulled down with 5,000 N of gravitational force while driving on the road.
Draw a free body diagram.
Calculate the net force. Determine the direction of acceleration if it is accelerating.

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.
