Mechanical EngineeringQ&A Library14-25. The 5-lb cylinder is falling from A with a speed VA = 10 ft/s onto the platform. Determine the maximum displacement of the platform, caused by the collision. The spring has an unstretched length of 1.75 ft and is originally kept in compression by the 1-ft long cables attached to the platform. Neglect the mass of the platform and spring and any energy lost during the collision. VA = 10 ft/s 3 ft k= 400 lb/ft 1 ftStart your trial now! First week only $4.99!*arrow_forward*
