A mass on a spring oscillates back and forth and completes one cycle in sec. Its maximum displacement is cm. What is the equation that models this motion? Choose the equation that models the displacement d after t seconds. 2. The wheel in a piston linkage has a radius of in. It turns with an angular velocity of rad/sec. The initial position is shown. What is the frequency of the piston? cycles/sec What is the distance from the initial position seconds after starting? in (Round to the nearest hundredth.) YOU ANSWERED: 3. The period P of a pendulum and its length L are related by P 2 where P is in seconds and L is in feet. How long should a pendulum be to have a period of seconds? The length should be feet.

The position of a weight attached to a spring is s(t) cos t inches after t seconds. Determine the maximum height the weight rises above the equilibrium position, the frequency and period of the system, and when the weight first reaches its maximum height. Then calculate and interpret s( ). What is the maximum height that the weight rises above the equilibrium position? in What is the frequency of the system? cycles per sec (Simplify your answer. Type an exact answer, using as needed.) What is the period of the system? sec (Simplify your answer. Type an exact answer, using as needed.) When does the weight first reach its maximum height? sec (Type an integer or fraction. Type an exact answer, using as needed.) Next, find s( ). s( ) in (Round to the nearest integer.)
