Question

2. Refer to the diagram shown here (a side view, not to scale) Two blocks with masses m, and m2, respectively, are connected via a massless thread over a pulley wheel. The wheel is a solid uniform disk with mass m, outer radius R, and a frictionless axle Initially you hold m, (and therefore the entire system) at rest in the position shown; m, is at rest on level ground. Then you release m The data: m,-7.16kg m2-3.45 kg m,-2.63 kg R=5.10cm F-27 .4 cm g=9.80 m/s2 a. By what percentage does the tension force acting on m, change when you release m2? b. How fast, measured in rpm, is the wheel spinning when m, reaches the surface? You may ignore air drag. (ground)

    Two blocks with masses m1 and m2 are connected by a massless string over a frictionless pulley. Block 1 sits on a frictionless horizontal surface and block 2 sits on a plane inclined at an angle θ above the horizontal. The coefficient of friction between block 2 and the incline is µk. The pulley, which is a uniform disk, has a mass mp and a radius R. When you release the blocks, both blocks slide without the string slipping on...

    Two blocks of masses m_1 = 4 kg and m_2 = 5kg are connected by a massless string that passes over a massless frictionless pulley as shown in Fig. 6.34. Block m_1 is initially at rest on a smooth horizontal plane while block m_2 is at a height h = 0.75 m above the ground. Use conservation of mechanical energy to find the speed of the masses just before m_2 hits the ground.

  • Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane

    Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...
