What does it mean with the car accelerates but in the opposite direction of the car?​

When a car is slowing down, the acceleration and velocity are in opposite directions. The acceleration is negative.

When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration.

Explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
