I am having trouble with some questions:
-A particle undergoes simple harmonic motion. In SI units, the maximum velocity is twice the maximum displacement. What's the frequency?
a.) 0.4
b.) 0.2
c.) 0.1
d.) 0.3
-A bat emits a sound at a frequency of 30 kHz as it approaches a wall. The bat perceives the frequency of the echo as 30.9 kHz. The speed of sound is 340. The speed of the bat is closest to?
a.) 50 m/s
b.) 5 m/s
c.) 1 m/s
d.) 0.5 m/s
e.) 10 m/s
Thank you

1. A bat emits a sound at a frequency of 12 kHz as it approaches a wall. The bat detects beats such that the frequency of the echo is 860 Hz higher than the frequency the bat is emitting. The speed of sound in air is 340 m/s. The speed of the bat is closest to 2. A supersonic plane passes overhead at a speed of 823 m/s. If you hear the sonic boom (shock wave) 4 s after the...
A particle undergoes damped harmonic motion. The spring constant is 100 N/m; the damping constant is 8.0 x 10-3 kg∙m/s, and the mass is 0.050 kg. If the particle starts at its maximum displacement, x = 1.5 m, at time t = 0, what is the angular frequency of the oscillations?
A particle undergoes simple harmonic motion (SHM) in one dimension. The r coordinate of the particle as a function of time is r(t)Aco() where A is the called the amptde" and w is called the "angular frequency." The motion is periodic with a period T given by Many physical systems are described by simple harmonic motion. Later in this course we will see, for example, that SHM describes the motion of a particle attached to an ideal spring. (a) What...
A 0.109-kg particle undergoes simple harmonic motion along the horizontal x-axis between the points ㄨㄧ--0.279 m and X2 = 0.499 m. The period of oscillation is 0.557 s. Find the frequency, the equilibrium position, Xeq, the amplitude, A, the maximum speed, Vmax, the maximum magnitude of acceleration, amax, the force constant, k, and the total mechanical energy, Etot
A particle undergoes simple harmonic motion with amplitude 25 cm and maximum speed 4.8 m/s. If a stopwatch is started when the particle is pulled to its maximum position and released, what is the formula for the position of the particle as a function of time?
A block of mass 8.50 g on the end of spring undergoes simple harmonic motion with a frequency of 4.00 Hz. What is the spring constant of the spring? 5.369 N/m You are correct. Your receipt no. is 157-4288 Help: Receipt Previous Tries If the motion of the mass has an initial amplitude of 1.50 cm what is its maximum speed?. 3.770×101 cm/s You are correct. Your receipt no. is 157-4662 Help: Receipt Previous Tries The amplitude decreases to 0.416...
