Explanation:
Given:m = 1,250 kg
[tex]v_i[/tex] = 30 km/hr
F = 1,700 N
t = 10 s
Required:Final velocity
Equation:ForceF = ma
where: F - force
m - mass
a - acceleration
Accelerationa = [tex]\frac{v_f \:-\:v_i}{t}[/tex]
where: a - acceleration
[tex]v_i[/tex] - initial velocity
[tex]v_f[/tex] - final velocity
t - time elapsed
Solution:Solve for acceleration using the formula for forceF = ma
Substitute the value of F and m
(1700 N) = (1250 kg)(a)
a = [tex]\frac{1700\:N}{1250\:N}[/tex]
a = 1.36 m/s²
Solve for final velocity using the formula for accelerationConvert 30 km/hr to m/s= [tex]\frac{30\:km}{hr}\:×\:\frac{1000\:m}{1\:m}\:×\:\frac{1\:hr}{3600\:s}[/tex]
= [tex] 8.33 m/s [/tex]
Substitute the value of a, [tex]v_i[/tex] and ta = [tex]\frac{v_f \:-\:v_i}{t}[/tex]
[tex]1.36\: m/s² \:= \:\frac{v_f \:-\:8.33\:m/s}{10\:s}[/tex]
[tex](10 \:s)1.36\: m/s² \:= \:v_f \:-\:8.33\:m/s[/tex]
[tex]v_f\: =\: (10 \:s)1.36 \:m/s²\: + \:8.33\:m/s[/tex]
[tex]v_f \: =\: 13.6 \:m/s \:+\: 8.33\:m/s[/tex]
[tex]v_f\: =\: 21.93\: m/s[/tex]
Convert to km/hr= [tex]\frac{21.93\:m}{s}\:×\:\frac{1\:km}{1000\:m}\:×\:\frac{3600\:s}{1/:hr}[/tex]
= [tex]78.95\: km/hr[/tex]
Final answerThe velocity of the car after 10 s is 78.95 km/hrer

Technician A says that some pop-up roll bars may be reset if NOT damaged.
Technician B says that some convertibles have stationary roll bars.
Who is right?
Answer:hey
Explanation:
Both Technician A and Technician B are correct.
Technician A says that some pop-up roll bars may be reset if NOT damaged.
Technician B says that some convertibles have stationary roll bars.
What is the TechnicianPop-up roll bars are special bars that come up by themselves if the car rolls over or crashes. They do this to keep the people inside the car safe. If the roll bars are set off but not broken, they can usually be put back or moved back into their original position by following the correct reset steps.
Some convertibles have fixed roll bars. Stationary roll bars stay in one place and do not move or come out on their own, unlike pop-up roll bars. These stationary roll bars make sure the car's structure is strong and protect people in case the car rolls over. However, they don't have the ability to retract or pop up like some other designs.

Explanation:
A local environmental group is advocating for the use of permanent modular construction (PMC) for all new construction sites. Why might PMC be better for the environment than traditional construction techniques?
PMC materials are by definition sustainable and environmentally friendly.
The manufacture of PMC materials consumes less energy than traditional methods.
PMC buildings are smaller than traditional buildings, which means they have less impact on the environment.
Fewer workers need to be on-site, which means less disturbance of the environment.

Answer:
A career in mechanical engineering enables you to work in any given industry at any location in the world
The career path in mechanical engineering includes;
1) Obtaining a mechanical engineering degree, which is a pre-requisite for entry-level mechanical engineering jobs in industries such as manufacturing of aerospace products, government ministries, research and development, manufacturing of machinery, and engineering services
2) Get mechanical engineering (hands on experience. One of the most important criteria by which employers select candidates for mechanical engineering jobs is the level of hands on job exposure the applicant has obtained
Such experience can be obtained through internships which are normally included as part of the mechanical engineering degree program and through the use of applications that aid in engineering design such as Computer Aided Design applications
3) Obtain certification and licenses that show the level of knowledge acquired and the degree of field participation commitment a person as an applicant has.
Important certifications include those by the American Society for Mechanical Engineering (ASME), Green Business Certification Inc (GBCI)
4) Finding an employment as a mechanical engineer is an important step where the jobs are high paying and the competition is also high. As a new engineer, working under more senior engineers from one to four years is required from which point the level of responsibility assigned is gradually increased
5) In order to gain career advancement that lead to opportunities that are high paying, a person can obtain advanced degrees
