A 32 kg mass-spring system, with a spring constant of 250 N/m, is laid flat on a frictionless table. After being displaced and released from rest, the mass oscillates between the 0.35 m and 0.93 m mark on a meter stick. part b. What is the total mechanical energy of the mass-spring system?
part c. Once released, what are the period and frequency of the resulting motion?
part d. What is the speed of the system when the mass is a distance of 0.31 m from equilibrium?

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
