Second equation of motion
s = ut + ½at²
Where: a = acceleration (m/s²), s = displacement (m), t = time (s), u = initial velocity (m/s)
Solved example
Given: a = 7, t = 5, u = 10
Find: s (displacement (m))
- Formula: s = a·t²/2 + t·u
- Substitute the values: s = 10·5 + 5²·7/2
- Result: s = 137.5 m
Answer: s = 137.5 m
