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 and its velocity depends on time as v = 3t - t^2. Here, v is in m//s and t in second. Find (a) average velocity and (b) average speed for first five seconds.

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
