Explanation:

A 1 250 kg car moving at a velocity of 30 km/hr along EDSA is accelerated by a force of 1 700 N. What will be its velocity after 10 seconds? (Neglect friction)

Answers

The velocity of the car after 10 s is 78.95 km/hr

Explanation:

Given:

m = 1,250 kg

[tex]v_i[/tex] = 30 km/hr

F = 1,700 N

t = 10 s

Required:

Final velocity

Equation:Force

F = ma

where: F - force

m - mass

a - acceleration

Acceleration

a = [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 force

F = 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 t

a = [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/hr

What is a test?

A test can be defined as a group of questions that are designed and developed to elicit a specific information in the form of answer from an individual such as a student or an interviewee.

Thus, a test is primarily formulated by professionals, so as to assess the understanding of a person and as such, it is very necessary to spend a large amount of time to check the grammar and double check the work before turning in a test for submission.

Who is to blame climate change?Scientists have measured global temperatures for over a hundred years and see that the Earth is getting hotter. Ice core data suggests the Earth should actually be cooling if it were following its natural cycles. The trend can be best visualized by comparing each years average temperature with the long- term average. Figure 1 shows observations of the worlds annual average temperature made by the National Oceanic and Atmospheric Administration (NOAA). In recent decades, the years have always been hotter. Over geologic time, the Earths average temperature has changed as a result of the suns output, the tilt and position of the Earth in its orbit, and the concentration of greenhouse gases. Scientists have developed a good understanding of the natural variations in these factors by examining different data sources in order to estimate ancient temperatures. Observations tell us that these natural factors have not been changing over the last hundred years or so in a way that would explain the observed temperature increases.In contrast, greenhouse gases have been changing in a way that can explain the observed temperature increases. Figure 2 shows the change in atmospheric CO2 concentration over the last thousand years. At the Scripps Institute of Oceanography in Hawaii researchers have been sampling pristine mountaintop air every month since 1958. Their observations show that both the concentration and isotopic composition of CO2 is changing, and is consistent with manmade sources, including the carbon emissions from burning fossil fuels. The industrial revolution marked a drastic increase in CO2 concentrations in the atmosphere when humans began using fossil fuels on a large scale.Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. CO2 along with other gases are known as greenhouse gases. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.Give evidence and reasoning!! uses of crush in the farm Which wWord best completes this analogy?brim : hat as buckleA. buttonB. beltC. shirtD. zipper Match each subject in the left column with the appropriate form of verb 1. nosotros2.
