A car accelerates from rest (v. 0 m/s) with a constant acceleration of
a = 5m/s2 for 12 seconds. What is the final speed of the car after the
12 seconds?

Heya!!

For calculate final velocity, lets applicate formula

                                                [tex]\boxed{V=V_o+a*t}[/tex]

                                                 Δ   Being   Δ

                                            V = Final Velocity = ?

                                         Vo = Initial velocity = 0 m/s

                                          a = Aceleration = 5 m/s²

                                                 t = Time = 12 s

⇒ Let's replace according the formula:

[tex]\boxed{V=0\ m/s +5\ m/s*12\ s}[/tex]

⇒ Resolving

[tex]\boxed{V=60\ m/s}[/tex]

Result:

The velocity after 10 sec is 60 meters per second (m/s)

Good Luck!!
