A marble block of mass $2\, kg$ lying on ice when given a velocity of $6\, m/s$ is stopped by friction in $10s$. Then the coefficient of friction is-
$0.02$
$0.03$
$0.06$
$0.01$
In a tonga, horse pulls a wagon. Which is the correct analysis of the situation?
To avoid slipping while walking on ice, one should take smaller steps because of the
A cylinder of mass $10\,kg$ is sliding on a plane with an initial velocity of $10\,m/s$. If coefficient of friction between surface and cylinder is $ 0.5$, then before stopping it will describe ............. $\mathrm{m}$
A conveyor belt is moving at a constant speed of $2\, ms^{-1}$. A box is gently dropped on it. The coefficient of friction between them is $\mu = 0.5$. The distance that the box will move relative to belt before coming to rest on it, (taking $g = 10\, ms^{-2}$) is ........ $m$.
A hockey player is moving northward and suddenly turns westward with the same speed to avoid an oopponent. The force that acts on the player is
