An automobile can be considered to be mounted on four identical springs as far as vertical oscillations are concerned. The sprin
tresset_1 [31]

Answer:

a) 120341 N/m

b) 1.432 Hz

Explanation:

Given that

Frequency of oscillations of spring, F = 3.27 Hz

Mass of the car, m = 1140 kg

Average mass of passengers, M = 68 kg

The mass on each spring,

m = 1/4 m,

m = 1140 / 4

m = 285 kg

The spring constant on each spring, k is

ω = √(k/m), also,

ω = 2πf, so that

2πf = √(k/m)

If we square both sides, then

4π²f² = k/m

k = 4π²f²m if we substitute, we have

k = 4 * 3.142² * 3.27² * 285

k = 120341 Nm

Since the mass of each person is 68 kg, then the total mass of all passengers would be

68 * 5 = 340 kg

Thus, the total mass of the oscillating system is,

mass of passengers + mass of car

340 kg + 1140 kg

M(total) = 1480 kg

To get the vibrating frequency, we substitute for values in the equation

2πf = √(k/m)

F = 1/2π * √(k/m)

F = 1/2π * √(120341 / 1480)

F = 1/2π * √81.31

F = 0.1591 * 9

F = 1.432 Hz

A wave has a distance between its peaks of 0.4 meters at a speed of 10 meters per second. What is the wave's frequency, in hertz
REY [17]

Answer: 25Hz

Explanation:

Given that:

Wavelength (λ) = 0.4m (the distance between the peaks of a wave is known as wavelength)

Frequency F = ?

Speed of wave V = 10 m/s

The wave frequency is the number of cycles which the wave complete in one second. It is measured in hertz, and represented by the symbol F

So, apply the formula V = F λ

10m/s = F x 0.4m

F = 10m/s / 0.4m

F = 25Hz

Thus, the frequency of the wave is 25 Hertz.
