A man pushes on a piano with mass 180 kg so that it slides at constant velocity down a ramp that is inclined at 11 degrees above the horizontal floor. Neglect any friction acting on the piano. Calculate the magnitude of the force applied by the man if he pushes (a) parallel to the incline. 2. Find the tension in each cord in Fig. E5.7 if the weight of the suspended object is w. 3. Atwood’s Machine. A 15.0-kg load of bricks hangs from one end of a rope that passes over a small, frictionless pulley. A 28.0- kg counterweight is suspended from the other end of the rope, as shown in Fig. E5.15. The system is released from rest. (a) What is the magnitude of the upward acceleration of the load of bricks? 4. Two crates connected by a rope lie on a horizontal surface (Fig. E5.35). Crate A has mass 𝑚 and crate B has mass 𝑚 . The coefficient of kinetic friction between each crate and the surface is 𝜇 . The crates are pulled to the right at constant velocity by a horizontal force In terms of 𝑚 , 𝑚 and 𝜇 calculate (a) the magnitude of the force. 5. Stay Dry! You tie a cord to a pail of water, and you swing the pail in a vertical circle of radius 0.600 m. What minimum speed must you give the pail at the highest point of the circle if no water is to spill from it? References : Young, Hugh D., Freedman, Roger A.
