Question

An object covers a distance of 'S' metres in 't' seconds as follows:
40
60
Distance (metres)
BO
100
11
2
Time (seconds)
4.
8
10
1
Plot a distance time graph for the given data and calculate the distance covered by the object
end of 5 s und 7.55​

Answer 1

Answer:

Magnitude of area under the v−t graph gives the distance travelled by the body.

For  0≤t≤4 s :

Displacement  S1= Area =21×(20+40)×2+21×(1+2)×20=90 m

For  4≤t≤5 s :

Displacement  S2= Area =21×1×20=10 m

Total distance d=S1+S2=90+10=100 m

Option A is correct.
