En un lago una lancha de motor que parte del reposo acelera en línea recta con una tasa constante de 3.0 m/s2 durante 8.0 s. ¿Qué distancia recorre en ese tiempo?

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
