Use this equation: |
Units will be: |
|
Final
velocity (vf), initial velocity (vi),
and time (t) |
Acceleration
(a) |
a
= (vf – vi) ¸ t |
m/s2 |
|
Acceleration
(a), final velocity (vf), initial
velocity (vi) |
Time
(t) |
t
= (vf – vi) ¸ a |
s |
|
Acceleration
(a), time (t), initial
velocity (vi) |
Final
velocity (vf) |
vf = vi + (a ´ t) |
m/s |
|
Acceleration
(a), time (t), final
velocity (vf) |
Initial
velocity (vi) |
vi
= vf – (a ´
