Answer:
Explanation:
1.
vf = vi + a(t)
vi = 0 m/s
a = 17/13
= 1.3 m/s^2
2.
F = M * a
= 15 * 1.3
= 19.62 N
3.
Normal force, Fn = m * g
= 15 * 9.8 m/s²
= 147 N.
Then find the maximum force of friction, knowing that μs = 0.76
Ff = Fn × μs
= 147 * 0.76
= 111.83 N
Maximum acceleration,
Ff = m × a
111.83 = 15 * a
a = 7.4556 m/s²
4.
In order to find the acceleration for the box, you need to know the net force of the box moving in the x direction and the frictional force, and you will end up with the Force of the vehicle minus the Frictional force (Ff) between the box and the vehicle, resulting your net force in the x direction.
F = m*a and Ff = μ * N
m*a = μk * N
m*a = μk * m * g
a = μk * g
a = 0.61 * 9.81
5.98 m/s^2 for the acceleration of the box on top of the vehicle.
5.
Assuming the box has re settled and is no longer sliding when braking begins and the surface remains horizontal, the maximum negative acceleration will again be
a = -7.4556 m/s².
Answer:
Explanation:
Given:
- width of door,
- height of the door,
- thickness of the door,
- mass of the door,
- torque on the door,
<em>∵Since the thickness of the door is very less as compared to its other dimensions, therefore we treat it as a rectangular sheet.</em>
- For a rectangular sheet we have the mass moment of inertia inertia as:
We have a relation between mass moment of inertia, torque and angular acceleration as:
Answer:
to be honest I'm not sure
Answer: 3 significant digits
Explanation:
When a number is written in <u>scientific notation</u> (representing the number using powers of base ten) it is expressed so that it contains a digit in the place of the units and all other digits after the decimal point, multiplied by the respective exponent.
Then, the significant figures (or significant digits) will be the digits that are before the power of ten.
For example, the number has <u>4 significant figures</u>.
Now, in the case of the number it contains <u>3 significant figures.</u>
A process called digitization converts analog sound waves into digital sound.

What is sound wave?</h3>
Sound wave is a longitudinal wave that requires a material medium for its propagation.
<h3>What is Digitization?</h3>
Digitization is the process through which information is converted into digital format.
- Digitization involves the conversion of the analog signal to the digital signal.
- The information is converted into discrete units of data, called bit.
Thus, a process called digitization converts analog sound waves into digital sound.
