- Bruce Lee was famous for breaking concrete blocks with a single karate chop. From slow-motion video, the speed of his 1.50-kg hand descending on a block was estimated to be 15.0 m/s, which decreased to a speed of 0.500 m/s in the 2.50 103 s during which his hand made contact with and broke through the block. The maximum shear stress a concrete block can be subjected to before breaking is 9.50 105 N/m2. a. What was the force exerted by Lees hand on the block? b. If a typical concrete block broken by Lee was 3.00 cm thick and 15.2 cm wide, what is the shear stress experienced by the concrete block? c. Will the concrete block succumb to Lees karate chop?arrow_forwardA spring, with a spring constant of 750 N/m, is hung vertically from the ceiling. If a mass of 500 kg is added to this spring, how much will it elongate?arrow_forwardTo measure the static friction coefficient between a 1.40-kg block and a vertical wall, a spring (k = 770 N/m) is attached to the block, is pushed on the end in a direction perpendicular to the wall until the block does not slip downward (see figure). If the spring is compressed by 0.048 m, what is the coefficient of static friction?arrow_forward
- A bar weighing 26.0 N is supported horizontally on each end by two hangingsprings, each 15.0 cm long, with spring constants 0.970 N/cm and 1.45 N/cm,respectively. The bar is 6.00 m long and has a center of mass 2.00 m from thespring with constant 0.970 N/cm. How far does each spring stretch?arrow_forwardA vertical spring has a force constant of 150 N/m. By how much will the spring be compressed if a mass 1.30 kg is placed on top of it?arrow_forwardwe analyzed a cable used to support an actor as he swings onto the stage. Now suppose the tension in the cable is 940 N as the actor reaches the lowest point. What diameter should a 10-m-long steel cable have if we do not want it to stretch more than 0.50 cm under these conditions?arrow_forward
- A spring is 16.5 cm long when it is lying on a table. One end is then attached to a hook and the other end is pulled by a force that increases to 22.0 N, causing the spring to stretch to a length of 19.0 cm. How long will the spring be if the 22.0 N force is replaced by a 44.0 N force?arrow_forwardA cable is 100 m long and has a cross-sectional area of 1.0 x 10-6 m2. A 1000 N force is applied to stretch the cable. The elastic modulus for the cable is 1.0 × 1011 N/m2. How far does it stretch?arrow_forwardA spring (k888 N/m) is hanging from the ceiling of an elevator, and a 7.1 kg object is attached to the lower end. By how much does the spring stretch (relative to its unstrained length) when the elevator is accelerating upward at a 0.74 m/s²?arrow_forward
- Two identical, side-by-side springs with spring constant 240 N/m support a 2.00 kg hanging box. Each spring supports the same weight. By how much is each spring stretched?arrow_forwardConsider the figure above, where a rigid beam of negligible mass and 10 m long is supported by a cable attached to a spring. When NO block is hung from the beam, the length L (cable-spring) is equal to 5 m. Assume that immediately after block (weight of 260 N) is hung at the end of the beam the spring does not stretch, calculate the tension under this assumption. Using this tension find how much the spring stretches. Express the amount the spring is stretched in cm. k =8275 N/m.arrow_forwardA 1.48 kg object is placed on the end of a vertical spring, with a spring constant of 103.9 N/m. How far will it stretch?arrow_forward
