- A spring with a spring constant 2.40 N/m attached to a block and the block is initially at rest with the mass of 40.0 kg. Later on, the block is pushed 5.00 m horizontally on arough floor with a constant spring force of 130 N. Spring is also stretched 5.00 m after doing work on the block. There is coefficient of friction between the block and floor, which has a value of 0.300. You are required to find the following:(a) Work done by the spring force and the applied force(b) Thermal energy in the block-floor system due to friction(c) Work done by the normal force and the gravitational force(d) The change in kinetic energy of the block(e) The final speed of the box(f) What type of friction do you see in this system?arrow_forwardWhen an 8.00-kg stone is at rest on a spring, the spring is compressed by 10.0 cm.

Sports scientists find that (on average) the knee extensor tendons in sprinters stretch 45 mm while those of nonathletes stretch only 32 mm. The spring constant of the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes?
