Question

An airplane starts from rest and moves with a uniform acceleration of 3.0 m/s^2 for 30.0s before leaving the grpund. Determine its displacement.

Answer 1

S = ut + 0.5at²
= 0 + [0.5 × 3 m/s² × (30 s)²]
= 1350 m

Displacement of airplane is 1350 m

Answer 2

its displacement is =1/2at²
1/2×3×30×30
1350
