1.	Find the distance travelled by the body from 4 s to 10 s in the given graph
Answer» Magnitude of area under the v−t graph gives the distance travelled by the body.For 0≤t≤4 s :DISPLACEMENT S 1 = Area = 21 ×(20+40)×2+ 21 ×(1+2)×20=90 mFor 4≤t≤5 s :Displacement S 2 = Area = 21 ×1×20=10 mTotal distance d=S 1 +S 2 =90+10=100 m
