An object with weight W is dragged along a horizontal plane by a force acting along a rope attached to the object. If the rape makes an angle with the plane, then the magnitude of the force is F= u sin() + cos(8) where u is a constant called the coefficient of friction. (a) Find the rate of change of F with respect to(0). - W( cos A-sin) (usin 0 + cos 0) df de- (b) When is this...

im A rope at an angle θ with the horizontal is pulled with a force UF. It pulls, in turn, two blocks, the bottom with mass M and the top with mass m. The coefficients of friction are p, between the top and bottom block (assume that they do not slide for the given force ) and pu between the bottom block and the table. Remember to show (and possibly evaluate) all forces acting on both blocks, including internal forces...

A mass M slides upward along a rough plane surface inclined at angle to the horizontal. Initially the mass has a speed V before it slides a distance Lup the incline. The coefficient of kinetic friction between the mass and the incline is *. While sliding, the acceleration of the mass is: Directed upward along the incline Directed downward along the incline Determined by the force of gravity on the mass Determined by the frictional force on the mass Determined...

A block of mass M is pulled with a rope that exerts a force of a magnitude F, causing it to slide over horizontal ground with kinetic coefficient of friction p (use "mu" when you input your answer). The force is applied at angle theta (use "theta" when you input your answer) above the horizontal shown below. Resolve F into components using the coordinate system shown: F_x, F_y =, Find the sum of the force components in the y-direction acting...

A mass M slides downward along a rough plane surface inclined at angle \Theta\: Θ = 29.8 in degrees relative to the horizontal. Initially the mass has a speed V_0\: V 0 = 5.32 m/s, before it slides a distance L = 1.0 m down the incline. During this sliding, the magnitude of the power associated with the work done by friction is equal to the magnitude of the power associated with the work done by the gravitational force. What...
