First equation of motion
v = u + at
Where: a = acceleration (m/s²), t = time (s), u = initial velocity (m/s), v = final velocity / speed (m/s)
Solved example
Given: a = 7, t = 5, u = 10
Find: v (final velocity / speed (m/s))
- Formula: v = a·t + u
- Substitute the values: v = 10 + 5·7
- Result: v = 45 m/s
Answer: v = 45 m/s
