A gun applies a force $F$ on a bullet which is given by $F =\left(100-0.5 \times 10^{5} t \right) N$. The bullet emerges out with speed $400 \,m / s$. Then find out the impulse exerted till force on bullet becomes zero. (in $N - s$)

A girl riding a bicycle along a straight road with a speed of $5\,ms^{-1}$ throws a stone of mass $0.5\, kg$ which has a speed of $15\,ms^{-1}$ with respect to the ground along her direction of motion. The mass of the girl and bicycle is $ 50\, kg$. Does the speed of the bicycle change after the stone is thrown ? What is the change in speed, if so ?

In a carom-board game the striker and the coins are identical and of mass $m$ . In a particular hit the coin is hit when it is placed close to the edge of the board as shown in figure such that the coin travels parallel to the edge. If the striker is moving with speed $v$ before the strike, then the net impulse on the striker during collision if it moves perpendicular to the edge after collision, is (assume all collisions to be perfectly elastic)
