Final Velocity (Constant Acceleration)
Final Velocity (Constant Acceleration)
Under constant acceleration the velocity rises linearly with time — the first equation of motion.
The final velocity is v = u + a·t. where u is the initial velocity, a the acceleration and t the time.
Inputs
u := 10 m/s=10 m/s
a := 3 m/s^2=3 m/s^2
t := 5 s=5 s
Add the velocity gained to the initial velocity.
v := u + a·t=25 m/s
Results
The car reaches 25 m/s after 5 s. A negative acceleration (deceleration) would reduce the velocity instead.
Assumptions & limitations
- Constant acceleration.
- Straight-line motion.
- Consistent direction.
