(A) :A body can have acceleration even if its velocity is zero at a given instant of time. (R) : A body is momentarily at rest when it reverses its direction of motion.

Two particles A and B get 4m closer each second while travelling in opposite direction. They get 0.4 m closer every second while travelling in same direction. The speeds of A and B are respectively&nbsp;

A motion boat covers a given distance in 6 h moving down stream of a river. It covers the same distance in 10&nbsp;h moving upstream. The time (in hour) it takes to cover the same distance in still water is

A freely falling body traveled xn in nth second distance travelled in n-1th second is
