A body of mass 2 kg is being dragged with uniform velocity of 2 m/s on a rough horizontal plane. The coefficient of friction between the body and the surface is 0.20. The amount of heat generated in 5 sec is (J=4.2 joule/cal and $\;g = 9.8\;m/{s^2})$

A marble block of mass 2 kg lying on ice when given a velocity of $6\;{\rm{m}}{{\rm{s}}^{ - 1}}$ is stopped by friction in 10 s. Then the coefficient of friction is

A block is projected up a frictionless inclined plane with initial speed $u$. The distance it travels up the incline before coming to rest is:

A cylinder of mass 10kg 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

A man of mass 60 kg and a boy mass 30 kg are standing together on frictionless ice surface. If they push each other apart, man moves away with a speed of $0.4\;{\rm{m}}{{\rm{s}}^1}$ relative to ice after 5 s. They will be away from each other at a distance of

Two blocks of masses $m_1$ and $m_2$ are connected by a light string passing over a frictionless pulley at the top of a smooth inclined plane of angle $heta$. If $m_1 > m_2\sinheta$, what is the acceleration of the system?

A block slides down a frictionless inclined plane of inclination $heta$. If $g$ is the acceleration due to gravity, its acceleration down the plane is:

A solid cylinder of mass $M$ and radius $R$ rolls without slipping down a rough inclined plane of angle $heta$. A block of the same mass $M$ slides down a frictionless inclined plane of the same angle $heta$. If both start from rest at the same height, what is the ratio of the linear speeds of the cylinder and the block when they reach the bottom?

A man drags a block through 10m on rough surface $\left( {\mu = 0.5} \right)$. A force of $\sqrt 3$ kN acting at ${30^0}$ to the horizontal. The work done by applied force is
