Concept explainers
Charging a Capacitor See the illustration. If a charged capacitor is connected to a coil by closing a switch, energy is transferred to the coil and then back to the capacitor in an oscillatory motion. The voltage (in volts) across the capacitor will gradually diminish to 0 with time (in seconds).
(a) Graph the function relating :
(b) At what times will the graph of touch the graph of ? When does the graph of touch the graph of ?
(c) When will the voltage be between volt?

- Oscillating Spring A mass attached to a spring oscillates upward and downward. The displacement of the mass from its equilibrium position after t seconds is given by the function d=3.5cos(2t). where d is measured in centimeters (Figure 13). a. Sketch the graph of this function for 0t5. b. What is the furthest distance of the mass from its equilibrium position? c. How long does it take for the mass to complete one oscillation?arrow_forwardOscillation of a Spring A ball that is bobbing up and down on the end of a spring has a maximum displacement of 3 inches. Its motion (in ideal conditions) is modeled by y=14cos16t,t0, where y is measured in feet and t is the time in seconds. (a) Graph the function. (b) What is the period of the oscillations? (c) Determine the first time the weight passes the point of equilibrium y=0.arrow_forwardAPPLICATIONS Shock Absorber When a car hits a certain bump on the road, a shock absorber on the car is compressed a distance of 6 in., then released see figure. The shock absorber vibrates in damped harmonic motion with frequency of 2 cycles per second. The damping constant for this particular shock absorber is 2.8. a Find an equation that describes the displacement of the shock absorber from its rest position as a function of time. Take t=0 to be the instant that the shock absorber is released. b How long does it take for the amplitude of the vibration to decrease to 0.5 in.?arrow_forward
