The kinematic equation that has all of our variables is d = Vi*t + 0.5*a*t^2
y = 15*2 + 0.5*9.8*2^2 = 49.6 m

A motorcycle stops at a red light and then gains a speed of 12 m/s in 15s. What's its acceleration?
erastova [34]

Option a) 0.8 m/s² is the correct answer

the acceleration of the motorcycle is 0.8 m/s²

Given the data in the question;

Since the motorcycle stopped then, initial speed u = 0 m/s

final speed v = 12 m/s

time t = 15 s

acceleration = ?

To get our acceleration, we use the first equation of motion.

This equation states that;

v = u + at

so, we simply substitute in our given values

12 m/s = 0 m/s + ( a * 15s )

12 m/s = ( a * 15 s )

so we find a

a = \frac{12m/s}{15s}

a = 0.8 m/s^2

Therefore, the acceleration of the motorcycle is 0.8 m/s²

Option a) 0.8 m/s² is the correct answer

If, as is typical, each of them breathes about 500 cm3 of air with each breath, approximately what volume of air (in cubic meter
deff fn [24]

Answer:

<em>a) 12614.4 m^3</em>

<em>b) 28.8 m</em>

Explanation:

The complete question is

Four astronauts are in a spherical space station. (a) If, as is typical, each of them breathes about 500 cm^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year? (b) What would the diameter (in meters) of the space station have to be to contain all this air?

The average breathing rate is 12 breaths per minute

there are 60 minutes x 24 hours x 365 days in a year = 525600 minutes in a year

if an average human takes 12 breath per minute, then in a year an average human take 12 x 525600 = 6307200 breath

For the four astronauts, the amount of breath = 4 x 6307200 = 25228800 breath in total.

The volume of air per breath = 500 cm^3

1 cm^3 = 10^-6 m^3

500 cm^3 = x m^3

x = 500 x 10^-6 = 5 x 10^-4 m^3

Therefore in a year, the volume of these astronauts breath in a year = 5 x 10^-4 x 25228800 = <em>12614.4 m^3</em>

b) If the space station is spherical, the volume will be given as = \frac{4}{3} \pi r^3

where r is the radius of the space station

This volume of the space station must be able to contain all the volume of breath produced by the astronauts which is = 12614.4 m^3

Equating, we have

12614.4 = \frac{4}{3} \pi r^3

12614.4 = \frac{4}{3}*3.142*r^3

12614.4 = 4.1893r^{3}

r^{3} = 12614.4/4.1893 = 3011.1

r = \sqrt[3]{3011.1} =<em> 14.4 m</em>

<em>diameter of the space station = 14.4 m x 2 =  28.8 m</em>
