2. A car accelerates from rest at a rate of 6 m/s^2 until it has traveled a total of 42 m. a). What is the velocity of the car once it has traveled 42 m?

it is a negative acceleration

+15-35=-20

going in opposite directions

3. dark matter

empty space could also be a simple vacuum

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
