The variation of velocity of a particle moving along straight line is shown in figure. The distance traversed by the body in 4 seconds is
Text Solution
Verified by ExpertsThe correct answer is:
D
distance travelled by the body in 4 sec.
= area under v – t graph
= 
× 1 × 20 + 1 × 20 + 2 × 10 + 
× 1 × 10
= 10 + 20 + 20 + 5
= 55 m
