A body moves along a horizontal plane for which s = t^3 - 9t^2 + 24t , where t is time in seconds : (where υ denotes velocity) Column – I Column – II A) For t p) υ is decreasing B) For 2 q) υ is increasing C) For t > 3 r) s is decreasing D) For t s) s is increasing

Correct Answer is : a - s ; b - r ; c - q ; d - p

a - p , s ; b - r ; c - q ; d - p , r

a - s ; b - r ; c - q ; d - p , r

a - s ; b - r , s ; c - q ; d - p
