Given
Initial speed of bus, u = 0 ms-1
Final speed of bus, v = ?
Acceleration, a = 0.1 ms-2
Time, t = 2 min = 120 s
Distance travelled, s = ?
i) We know, v = u + at
or v = 0 + 0.1 × 120 = 12 ms-1
ii) To find distance travelled, we use the equation
S = ut + {tex}\frac12{/tex} at2
or S = 0 × 120 + {tex}\frac12{/tex}× 0.1 × (120)2 = 720 m
Therefore
Final speed acquired = 12 ms-1
Distance travelled = 720 m
