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)

A particle is moving in a circle with uniform speed $v$. In moving from a point to another diametrically opposite point

An object of mass $'m'$ is being moved with a constant velocity under the action of an applied force of $2\, {N}$ along a frictionless surface with following surface profile.

The correct applied force vs distance graph will be:

A ball of mass $0.15\; kg$ hits the wall with its initial speed of $12 \;ms ^{-1}$ and bounces back without changing its initial speed. If the force applied by the wall on the ball during the contact is $100\; N$. calculate the time duration of the contact of ball with the wall $.........cm$

A man is at rest in the middle of a pond on perfectly smooth ice. He can get himself to the shore by making use of Newton's

A force of $50\, dynes $ is acted on a body of mass $5 \,g$ which is at rest for an interval of $3 \,seconds$, then impulse is
