SHM and simple pendulum
A block – spring system consists of a spring with constant k= 425 N/m attached to a 2.00 - kg block on a frictionless surface. The block is pulled 0.08 m from equilibrium and released from rest. For the resulting oscillation, find the max acceleration.
What is 17 m/s?
if an object is traveling away from you, the velocity will have a _____ sign
negative
The mating call of a male cicada is among the loudest noises in the insect world, reaching decibel levels of 110 dB at a distance of 2.00 m from the insect. Calculate the corresponding sound intensity.
What is 0.1 W/m2?
Transverse waves with a speed of 50.0 m/s are to be produced on a stretched string. A 5.00 m length of string with a total mass of 0.08 kg is used. What is the required tension in the string?
What is 40 N?
A simple pendulum has a length of 0.52 m and makes 82.0 complete oscillations in 200 s. Find the value of g at the location of the pendulum.
What would the doppler effect formula look like if two objects were moving away from each other?
What is fo=f((v + vs)/(v - vo))?
If you increase the sound level by 20 dB, how does the intensity of the sound change?
What is 100x intensity?
You are watching a baseball game from the bleachers behind the outfield wall, 118 meters from the batter. After you see the batter hit the ball, you hear the crack of the bat 0.36 seconds later. What is the temperature? (Give answer in either Kelvin or Celsius.)
What is -5.4 C or 268K?
A 8 kg block is attached to a spring with a spring constant of 125 N/m. The block slides back and forth on a smooth horizontal table, with the other end of the spring fixed to a wall. You displace the block 0.07 meters away from the equilibrium position and let go of the block. What is the period of the oscillations for the spring-mass system?
A train moving at a speed of 40.0 m/s sounds its whistle, which has a frequency of 500 Hz. Determine the frequency heard by a stationary observer as the train approaches the observer. The temperature is 24.0°C.
What is 566 Hz?
Ten marching band members play their trumpets, and all produce a sound with an equal intensity. The audience hears the song played at a decibel level of 110 dB. How many decibels would the audience hear if only one trumpet player begins playing a solo?
What is 100 dB?
A simple pendulum consists of a ball of mass 5.00 kg hanging from a uniform string of mass 0.06 kg and length L. If the period of oscillation of the pendulum is 2.00 s, determine the speed of a transverse wave in the string when the pendulum hangs vertically
A 0.6 kg block is released from rest and slides down a frictionless track that begins 2.00 m above the horizontal. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 30.0 N/m. Find the maximum distance the spring is compressed.
What is 0.89 m?
An ambulance travels down a highway at a speed of 15.0 m/s, its siren emitting sound at a frequency of 300 Hz.
What frequency is heard by a passenger in a car traveling at 10 m/s in the opposite direction as the car and ambulance approach each other?
What is 323 Hz?
A single tornado siren makes a 130 dB noise at a distance of 50 meters. Treat the siren as a point source emitting a spherical wave. What is the power output of the tornado siren?
What is 314,000 W?
Taylor Swift has a simple pendulum. When it swings back and forth, the period of this pendulum is 3.2 seconds while on Earth. Kanye West steals Taylor’s pendulum, boards a spaceship, and travels to his home planet in a faraway unknown galaxy. On Kanye’s home planet, the same pendulum now has a period of 4.5 seconds. What is the acceleration of gravity on Kanye’s home planet?
What is 4.96 m/s?
Assume a speed of sound of 343 m/s. A bat uses echolocation to hunt. The bat flies with a speed of 8 m/s towards a moth. The moth flies 5 m/s towards the bat. If the bat emits a chirp of frequency 32000 Hz, what frequency will the bat hear after the sound echoes off the moth and returns to the bat?
What is 34,500 Hz?
The mating call of a male cicada is among the loudest noises in the insect world, reaching decibel levels of 115 dB at a distance of 2.00 m from the insect. Calculate the decibel level at a distance of 20.0 m from 100 male cicadas each producing the same sound intensity.
What is 115 dB?
