The variation of velocity of a particle moving along a straight line is illustrated in the following figure. The distance covered by the particle in 4 seconds is :

Answer

A

Explanation

After `t=1` sec, the speed increases with
`a=g sin 37^(@)=6 m//s^(2)`
`:. V_(y)=g sin 37^(@)xx1=6 m//s`
`:.` speed `=sqrt(8^(2)+6^(2))=10 m//s`
