A pinball launcher is a spring with spring constant k = 65.0 N/m. It is compressed a distance of 8.00 cm and a ball of mass 0.100 kg is placed in front of it. When the spring is released, the ball rolls up the incline of the pinball machine. Assuming that it does not hit anything and that no energy is lost to friction, what vertical height does the ball gain before coming momentarily to rest?

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
