- The force of wind blowing on a window positioned at a right angle to the direction of the wind varies jointly as the area of the window and the square of the wind's speed. It is known that a wind of 30 miles per hour blowing on a window measuring 4 feet by 5 feet exerts a force of 150 pounds. During a storm with winds of 60 miles per hour, should hurricane shutters be placed on a window that measures 3 feet by 4 feet and is capable of withstanding 300 pounds of force?A box of mass 8 kg sits on a horizontal tabletop. An unstretched spring of force con- stant 420 N/m runs between the box and a wall. The coefficient of friction between box and table is Another box of mass 10 kg 2 is hung from a string of negligible mass tied to the front of box 1, and allowed to fall from rest. 1420 N/m 8 kg =0.5 10 kg By what amount has the spring has been stretched when the acceleration of the boxes has magnitude 1 m/s²? Assume gravitational acceleration is 10 m/s². Answer in units of m.A rectangular block has a length that is five times its width and a height that is three times its width. The blocks surfaces are all identical except for size. When the block is placed on a horizontal tabletop so that the area in contact with the table is length width, it is found that a horizontal force of 10.0 N applied to the block is just sufficient to overcome the static friction force and cause the block to move. The block is then knocked over so that the area in contact with the table is length height. Now, what minimum horizontal force will cause the block to move? Explain.
