1.) A light horizontal spring has a spring constant of 182 N/m. A 2.93 kg block is pressed against one end of the spring, compressing the spring 0.144 m. After the block is released, the block moves 0.229 m to the right before coming to rest. The acceleration of gravity is 9.81 m/s2. a.) What is the coeficient of kinetic friction between the horizontal surface and the block? 2.) A mass-spring system oscillates with an amplitude of 3.3 cm. The spring constant is 251 N/m and the mass is 0.309 kg. a) Calculate the mechanical energy of the mass-spring system. Answer in units of J. b) Calculate the maximum acceleration of the mass-spring system. Answer in units of m/s2.
