The landing gear of an airplane can be idealized as the spring-mass-damper system shown in fig. 3.52. if the runway surface is described determine the values of k and c that limit the amplitude of vibration of the airplane (x) to 0.1 m. assume

Ben (55kg) is standing on very slippery ice when junior (25kg) bumps into him. junior was moving at a speed of 8 m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision. give the answer in m/s. describe the work you did to get the answer.
