Position of a particle at any instant is given by `x = 3t^(2)+1` , where x is in m and t in sec. Its average velocity in the time interval `t = 2` sec to `t = 3` sec will be :

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

If position of a particle at instant t is given by x=3t^(2) , find the velocity and acceleration of the particle.

If the particle is moving along a straight line given by the relation x=2-3t +4t^3 where s is in cms., and t in sec. Its average velocity during the third sec is

If the particle is moving along a straight line given by the relation x=2-3t +4t^3 where s is in cms., and t in sec. Its average velocity during the third sec is

A particle is moving along straight line whose position x at time t is described by x = t^(3) - t^(2) where x is in meters and t is in seconds . Then the average acceleration from t = 2 sec. to t = 4 sec, is :
