(26) A block of mass mi located on a horizontal frictionless surface is connected by a light non-stretchable cord that passes over a massless frictionless pulley to a second block of mass m2, which is allowed to move on an inclined friction- less plane of angle e, as shown in Fig. 5.37. Find the acceleration of the two blocks and the tension in the cord when mı = 2 kg, m2 =6 kg, sin 0 =4/5, and cos...
Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...

Consider the scenario shown in the diagram below. A box (mass m1) is on a slope, which is inclined at an angle theta with respect to the horizontal. The box is connected via a string and pulley to a hanging weight (mass m2). The string and the pulley are assumed to be massless and frictionless, but there is friction between the box and the incline (with coefficient of kinetic friction mu k). Find an expression for the tension T in...

A block M1 of mass 16.0 kgsits on top of a larger block M2 of mass 26.0 kg which sits on a flat surface. The kinetic friction coefficient between the upper and lower block is 0.400. The kinetic friction coefficient between the lower block and the flat surface is 0.100. A horizontal force F = 98 N pushes against the upper block, causing it to slide. The friction force between the blocks then causes the lower block to slide also....
A block of mass m1 = 1.95 kg and a block of mass m2 = 5.50 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg.
