Which one of the following statements is correct
Rolling friction is greater than sliding friction
Rolling friction is less than sliding friction
Rolling friction is equal to sliding friction
Rolling friction and sliding friction are same
$10\, kg$ block is placed as shown, if $F = 50$ newton find friction force ............ $N$
A body of weight $64\, N$ is pushed with just enough force to start it moving across a horizontal floor and the same force continues to act afterwards. If the coefficients of static and dynamic friction are $0.6$ and $0.4$ respectively, the acceleration of the body will be (Acceleration due to gravity $= g$)
It is difficult to move a cycle with brakes on because
A marble block of mass $2\, kg$ lying on ice when given a velocity of $6 \,m/s$ is stopped by friction in $10\,s$. Then the coefficient of friction is
A block $B$ is pushed momentarily along a horizontal surface with an initial velocity $V.$ If $\mu $ is the coefficient of sliding friction between $B$ and the surface, block $B$ will come to rest after a time
