If another block of mass M/2 is placed on the block and it is again pulled on the surface, the coefficient of friction between the block and the surface will be The magnitude of the frictional force acting on a block of mass m, pulled at a constant velocity along a rough horizontal floor by an applied force T, can be determined using the equation: Frictional force = coefficient of friction * normal force The normal force is the force exerted by the surface on the A block of mass m is connected to another block of mass M by a spring (massless) of spring constant k. The maximum extension of the spring is. `m u^(2)` C. The length of string between pulley and mass ′ m ′ must remain constant, In the given figure find the velocity of the block M, if both the rope ends are pulled with a velocity v. (a) What is the magnitude of the normal force in each case? Question: A block of mass m=1. Coefficient of friction between both the blocks and Two blocks of masses m and 2 m placed one over the other as shown in figure. Coefficient of friction between block and surface is μ. Then a Answer: Bottom string tension is mg, right string tension is mg/(sin α +cos α tanθ), left string tension is mg/(sinθ+cosθtan α) Problem # 3 A block of mass M is being pulled at constant A box with mass m is dragged across a level floor having a coefficient of kinetic friction µK by a rope that is pulled upward with an angle θ above the horizontal with a force of magnitude. • a) Find the magnitude of the acceleration of the block. The coefficient of kinetic friction is μ k , between block and surface. The coefficient of kinetic friction is Mka between block and surface. The m A block of mass m = 2kg is pulled along a rough horizontal surface by applying a constant force at an angle 0 = tan- 2 with the horizontal as shown in the figure.
