Answer:
this is it
Explanation:
For every 9 turns of the driver the follower will make 4 complete rotations!
Answer: 6s
Explanation:
Vs=32m/s speed at beginning of slowing down
Vf=0m/s stop speed
a= -6 m/s² acceleration
----------------
Use equation for acceleration :
a=(Vf-Vs)/t
a*t=Vf-Vs
t=(Vf-Vs)/a
t=(0-36)/-6
t=-36/-6
t=6 s
Answer:
Option C. 4 Hz
Explanation:
To know the correct answer to the question given above, it is important we know the definition of frequency.
Frequency can simply be defined as the number of complete oscillations or circles made in one second.
Considering the diagram given above, the wave passes through the medium over a period of one second.
Thus, we can obtain the frequency by simply counting the numbers of complete circles made during the period.
From the diagram given above,
The number of circles = 4
Thus,
The frequency is 4 Hz
Answer:
4.4694 meters per second, 74.4907 kilometers per hour.
The vertical distance through which the book falls is determined as 1,048.8 m.
<h3>Height of the book fall</h3>
The vertical distance through which the book falls is calculated as follows;
h = vt + ¹/₂gt²
where;
- h is height of fall
- v is initial vertical velocity
- g is acceleration due to gravity
h = (16 x sin52)(13.4) + (0.5)(9.8)(13.4²)
h = 1,048.8 m
Thus, the vertical distance through which the book falls is determined as 1,048.8 m.
