Acar accelerates from rest at -2.40 m/s2. (include the sign in your answers.) (a) what is the velocity at the end of 3.6 s?

Explanation:

We have equation of motion v = u + at

     Initial velocity, u  0 m/s

     Final velocity, v = ?  

     Time, t = 3.6 s

      Acceleration, a = -2.40 m/s²

     Substituting

                      v = u + at  

                      v = 0 + -2.40 x 3.6

                      v = -8.64 m/s

Velocity at the end of 3.6 s is -8.64 m/s
