In 0.510 seconds, there are 44 complete vibrations. To find the duration of a single vibration, divide 0.510 by 44, resulting in approximately 0.01159 seconds. Therefore, the period T equals 0.01159 seconds. The frequency f is given by 1/T, which calculates to about 86.28 Hz. The angular frequency ω is calculated as 2πf, resulting in approximately 542.11 rad/s.

To find the time required for one revolution, compute as follows:
0.510 s / 440 revolutions = 51/44000 s
. The frequency in Hertz is the reciprocal of this figure, resulting in a frequency of about 862.75 Hz.
The angular velocity in radians per second
is calculated as (440 rev / 0.510 s) x (2π rad / 1 rev) = 5420.787 rad/s
. The period, which is the inverse of frequency, is approximately equal to 1.16x10^-3 s.

Assume you are driving 20 mph on a straight road. Also, assume that at a speed of 20 miles per hour, it takes 100 feet to stop.
Maru [3345]

Answer:900 feet

Explanation:

Given

Velocity \left ( V_1\right )=20 mph\approx 29.334 ft/s

It takes 100 feet to come to a stop.

Utilizing the equation of motion

v^2-u^2=2as

Where

v,u=Final and initial velocities

a=acceleration

s=distance traveled

0-\left ( 29.334\right )^2=2\left (-a\right )\left ( 100\right )

a=\frac{29.334^2}{2\times 100}=4.302 ft/s^2

When the speed is 60 mph \approx 88.002 ft/s

v^2-u^2=2as

0-\left ( 88.002\right )^2=2\left ( -4.302\right )\left ( s\right )

s=900.08 feet

kicyunya [3294]

Response:

Velocity is defined as displacement divided by time.

Acceleration is defined as the change in velocity divided by time.

To determine average velocity, one can utilize multiple velocities and their combined time.

Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both d
Maru [3345]

Answer:

4.05 m/s

Explanation:

We will express the varying velocities as vectors.

Newton moves northward at 3.90 m/s from Daniel's stationary position.

V_n = 3.9 j

Assuming Pauli runs relative to Daniel at velocity X.

The relative velocity of Newton as seen by Pauli will be

3.9 j - X

Given that

the relative velocity of Newton with respect to moving Pauli = 1.1 i (1.1 towards the east).

Thus,

3.9 j - X = 1.1 i

X = -1.1 i + 3.9 j.

Magnitude of X

X² = 1.1² + 3.9²

X = 4.05 m/s

Therefore, Pauli runs relative to Daniel at 4.05 m/s.

The direction will be west of north at an angle θ,

Tan θ = 1.1 / 3.9
