A small block slides down a smooth inclined plane of angle $heta$ from a height $h$. It then smoothly transitions onto a horizontal surface with a coefficient of kinetic friction $\mu_k$. What is the distance the block travels on the horizontal surface before coming to rest?

A force of 98 N is required to just start moving a body of mass 100 kg over ice. The coefficient of static friction is

The minimum velocity (in ${\rm{m}}{{\rm{s}}^{ - 1}}$) with which a car driver must traverse a flat curve of radius 150 m and coefficient of friction 0.6 to avoid skidding is

A rectangular block has a square base measuring a×a, and its height is $h$. Its moves on a horizontal surface in a direction perpendicular to one of its edges. The coefficient of friction is $\mu$. It will topple if

A block of mass 5 kg is on a rough horizontal surface and is at rest. Now a force of 24 N is imparted to it with negligible impulse. If the coefficient of kinetic friction is 0.4 and $g = 9.8\;m/{s^2}$, then the acceleration of the block is

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?
