A toy car is given an initial velocity of 1.44 m/s and experiences a constant acceleration of 4.48 m/s2 . What is the final velocity after 8.55 s?

final velocity = 39.7 m/s

Explanation:

u = 1.44 m/s      a = 4.48 m/s²     t = 8.55 s        v = ?

                           v = u + at

                     v = 1.44 + (4.48 x 8.55)

                         = 39.7 m/s            

Hope this helps!

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
