Answer 2

Given :-

Initial velocity = 0 m/s

Acceleration = 5 m/s^2

Time = 5 seconds

To Find :-

Final velocity

Solution :-

We know :-

v = u + at

• v = final velocity
• u = initial velocity
• a = acceleration
• t = time

By substituting the values we get :-

$: \implies \sf v = 0 + 5 \times 5$

$: \implies \sf v = 25$

Final velocity = 25 m/s

Other formulas :-

• s = ut + 1/2at²
• v² = u² + 2as
