The momentum $p$ of an object varies with time $(t)$ as shown in figure. The corresponding force $(F)$-time $(t)$ graph is

Solution

(a)
$F=\frac{d p}{d t}=$ slope of $P-t$ curve
From $t=0$ to $t=2$ second slope is constant and positive
From $t=2$ to $t=6$ second slope is zero
From $t=6$ to $t=8$ second slope is constant and negative

A large number $(n)$ of identical beads, each of mass $m$ and radius $r$ are strung on a thin smooth rigid horizontal rod of length $L\, (L >> r)$ and are at rest at random positions. The rod is mounted between two rigid supports (see figure) . If one of the beads is now given a speed $v$, the average force experienced by each support after a long time is (assume all collisions are elastic)
