Required Answer:
Given:
- Initial velocity (u) = 10m/s
- Acceleration (a) = 4m/s²
- Time taken (t) = 10s
To calculate:
- The velocity acquired by the bike i.e its final velocity (v)
Calculation:
By using 1st equation of motion:
Where,
※v = final velocity
※ u = initial velocity
※ a = acceleration
※ t = time
Therefore,velocity acquired by the bike is 50m/s.

More information!
Equations of motion:
- v = u + at
- s = ut + ½at²
- v² – u² = 2as
Where,
★ v = final velocity = m/s
★ u = initial velocity = m/s
★ a = acceleration = m/s²
★ s = distance/displacement = m
★ t = time = sec
Remember that!
- When a body starts from rest, its initial velocity is 0.
- When a body comes to stop or applies breaks, its final velocity is 0.

u = 10 m/s
a = 4 m/s²
t = 10 s
We know,
v = u + at
⇒v = 10 m/s + (4 m/s²)(10 s)
⇒v = 10 m/s + 40 m/s
⇒v = 50 m/s
