The problem describes a car accelerating and a ball being dropped from its window. We need to find the velocity and acceleration of the ball at t=6 s.

The problem describes a car accelerating and a ball being dropped from its window. We need to find the velocity and acceleration of the ball at $t=6 \, \text{s}$.

Let's interpret the problem as follows: The car starts from rest and accelerates. At some time $t_{drop}$ (from the car's start), the ball is dropped. We are asked for the velocity and acceleration of the ball at a total time of $t=6 \, \text{s}$ from the car's start. This means the ball falls for a duration of $t_{fall} = 6 \, \text{s} - t_{drop}$.

Given:
