The average velocity of a particle moving on a straight line is zero in a time interval. Assertion :- It is possible that the instantaneous acceleration is never zero in the interval. Reason :- It is possible that the instantaneous velocity is never zero in the interval.

The block are of mass 2 kg shown is in equlibrium. At t=0 right spring in figure (i) and right string in figure (ii) breaks. Find the ratio of instantaneous acceleration of blocks ?

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

Define acceleration.
