In each of the questions below, hanging a mass m from a spring stretches the spring l meters from its unloaded length. calculate the spring constant k, write the differential equations that governs the motion of the undamped mass-spring system, and find the solution that satisfies the initial conditions specified. units are mks; the gravitational constant is 9.8 m/s2.

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects

Why are graphs useful when interpreting data

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
