A wooden block of mass m resting on a rough horizontal table is pulled by a force F as shown in figure. If k is the Coefficient of friction between block and table. What will be its acceleration?
(F cos(theta)-k(mg-Fsin(theta)))/m
A spherical shell of mass m is resting on the rough horizontal plane with a coefficient of friction 0.3 a horizontal force act at a distance of 5r/3 from the baseline where r is the radius of the sphere. Find work done by friction body has moved by a distance of gm/r from the initial position?
An object of mass m = 2 kg is lying on a rough inclined slope such that it is at rest. Find the magnitude of contact force acting on the object (in Newtons).
Assume g=10 Coefficient of friction = .8 Angle of elevation = 30
A simple pendulum with length l and bob of mass m execute simple harmonic motion of small amplitude A. What would be the maximum tension in the string?
A book is at rest on a horizontal table. The table is steadily and slowly tipped until the book begins to slide off the table. At what angle, in degrees, will the book begin to move?
Two blocks are held against the wall by applying a horizontal force as shown in the diagram. The wall is frictionless but the surface between the blocks is rough.
Can these blocks remain in the equilibrium, answer with explanation?
