A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E= 46.9 J and a maximum displacement from equilibrium of 0.201 m. (a) What is the spring constant? 1163.2 X N/m (b) What is the kinetic energy of the system at the equilibrium point? 0 X The correct answer is not zero. J (c) If the maximum speed of the block is 3.45 m/s, what is its mass? 420 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. kg (d) What is the speed of the block when its displacement is 0.160 m? 3.04 x Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (e) Find the kinetic energy of the block at x = 0.160 m. 1.95 x Your response differs from the correct answer by more than 10%. Double check your calculations. J (f) Find the potential energy stored in the spring when x = 0.160 m. 14.86 X Your response differs from the correct answer by more than 10%. Double check your calculations. J
