The Formula a = v 2 − v 1 t 2 − t 1 gives a vehicle's average acceleretion when its velocity changes from v 1 at time t 1 to v 2 at time t 2 . Solve for t 2 .

Question

The Formula   a  =                    v        2            −              v        1                            t        2            −              t        1             gives a vehicle&#039;s average acceleretion when its velocity changes from       v    1   at time       t    1   to       v    2   at time       t    2  . Solve for       t    2  .

a  =                    v        2            −              v        1                            t        2            −              t        1            Multiply both sides by   (      t    2    −      t    1    ), we get   (      t    2    −      t    1    )  a  =      v    2    −      v    1  Divide both sides by a,            (              t        2            −              t        1            )      a        a    =                    v        2            −              v        1              a          t    2    −      t    1    =      1    a    (      v    2    −      v    1    )        t    2    −      t    1    +      t    1    =      1    a    (      v    2    −      v    1    )  +      t    1          t    2    =      1    a    (      v    2    −      v    1    )  +      t    1

The formula a=(v_2-v_1)/(t_2-t_1) gives a vehicle's average acceleration when its velocity changes from v_1 at time t_1 to v_2 at time t_2. Solve for t_2.
