The position of an object moving on a straight line is defined by the relation x=t^(3)-2t^(2)-4t , where x is expressed in meter and t in second. Determine (a) the average velocity during the interval of 1 second to 4 second. (b) the velocity at t = 1 s and t = 4 s, (c) the average acceleration during the interval of 1 second to 4 second. (d) the acceleration at t = 4 s and

A particle moves along a straight line such that its position x at any time t is x=3t^(2)-t^(3) , where x is in metre and t in second the

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

The position of a particle moving along a straight line is defined by the relation, x=t^(3)-6t^(2)-15t+40 where x is in meters and t in seconds.The distance travelled by the particle from t=0 to t=2 s is?

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.

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.

A particle moves along a straight line its velocity dipends on time as v=4t-t^(2) . Then for first 5 s :

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
