A2.50-kg mass is pushed against a horizontal spring of force constant 25.0 n/cm on a frictionless air table. the spring is attached to the tabletop, and the mass is not attached to the spring in any way. when the spring has been compressed enough to store 11.5 j of potential energy in it, the mass is suddenly released from rest. find the greatest speed the mass reaches, when does it occur? what is the greatest acceleration of the mass and when does it occur?

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 Ă— 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)
