Initial velocity (u) = 2 m/s
Acceleration (a) = 10 m/s^2
Time taken (t) = 4 s
Let the final velocity be v.
By using the equation,
v = u + at, we get
or, v = 2 + 10 × 4
or, v = 2 + 40
or, v = 42
The final velocity is 42 m/s.
- initial velocity=u=2m/s
- Acceleration=a=10m/s^2
- Time=t=4s
- Final velocity=v
Using first equation of kinematics
