A hammer weighing $$3\,kg$$ strikes the head of a nail with a speed of $$2\,m{s^{ - 1}}$$ drives it by $$1\,cm$$ into the wall. The impulse imparted to the wall is
The figure shows the position-time $$\left( {x - t} \right)$$ graph of one dimensional motion of a body of mass $$0.4kg.$$ The magnitude of each impulse is
A rigid ball of mass $$m$$ strikes a rigid wall at $${60^ \circ }$$ and gets reflected without loss of speed as shown in the figure. The value of impulse imparted by the wall on the ball will be
The force $$F$$ acting on a particle of mass $$m$$ is indicated by the force-time graph shown below. The change in momentum of the particle over the time interval from $$0$$ to $$8 s$$ is
A man of $$50\,kg$$ mass is standing in a gravity free space at a height of $$10\,m$$ above the floor. He throws a stone of $$0.5\,kg$$ mass downwards with a speed $$2\,m{s^{ - 1}}.$$ When the stone reaches the floor, the distance of the man above the floor will be
