Download Solution PDFConcept:
- Speed is defined as the rate of change of distance i.e.,
\(\Rightarrow Speed (v) = \frac{Distance (d)}{time (t)}\)
- SI unit of speed is m/s and its dimension is [LT-1].
Calculation:
Given - Length of train = 200 m, length of bridge = 600 m
∴ Total distance (d) = 200 + 600 = 800 m
Speed of train (v) = 36 km/h = 10 m/s
\(\Rightarrow time (t)=\frac{Distance (d)}{speed(v)}=\frac{800}{10}=80\, s\,\)
