A particle moves along a straight line according to the law s=t^3/3 -3t^2+9t+17 , where s is in meters and t in second. Velocity decreases when

Position of a particle moving along a straight line is given by x=2t^(2)+t . Find the velocity at t = 2 sec.

A particle moves in a straight line obeying the relation x= t(t-1) where x= displacement in m and t= time in sec.Find the velocity of the particle when its displacement is zero.

The position of the particle moving along x-axis is given by x=2t-3t^(2)+t^(3) where x is in mt and t is in second.The velocity of the particle at t=2sec is

A particle moves alo g a straight line and its velocity depends on time as v=6t-3t^(2) where 'v' is in m/sec and 't' is in sec. find average velocity and average speed forr first four seconds.
