A body moving in the positive x direction passes the origin at time t = 0. between t = 0 and t = 1 second, the body has a constant speed of 24 meters per second. at t = 1 second, the body is given a constant acceleration of 6 meters per second squared in the negative x direction. the position x of the body at t = 11 seconds is
Integrate over [0, 1] to get the position of the body after 1 second. It starts at the origin, so we take x(0 s) = 0 m and using the fundamental theorem of calculus,
[tex]\displaystyle x(1\,\mathrm s) = x(0\,\mathrm s) + \int_{0\,\rm s}^{1\,\rm s} \left(24\frac{\rm m}{\rm s}\right) \, dt = 24 \, \mathrm m[/tex]
Then for time t ≥ 1 second, we integrate over [1, 11] to get the position after the next 10 seconds of motion. Since x(1 s) = 24 m, we have
[tex]\displaystyle x(11\,\mathrm s) = x(1\,\mathrm s) + \int_{1\,\rm s}^{11\,\rm s} \left(24\frac{\rm m}{\rm s} - \left(6\frac{\rm m}{\mathrm s^2}\right) t\right) \, dt = \boxed{-36\,\mathrm m}[/tex]
Without using calculus, in the 1st second of motion the body travels at constant speed, so it reaches a new position of
x = (24 m/s) (1 s) = 24 m
In the next 10 seconds, the body has constant acceleration and its velocity at time t is
v = 24 m/s - (6 m/s²) (t - 1 s)
so its "initial" velocity is 24 m/s, and after 10 seconds it attains a "final" velocity of
24 m/s - (6 m/s²) (11 s - 1 s) = -36 m/s
Then the body travels a distance x such that
(-36 m/s)² - (24 m/s)² = 2 (-6 m/s²) x ⇒ x = - 60 m
and so the body's net change in position is 24 m - 60 m = -36 m.
20.3 applying the zero product property to solve equations
Explanation:
The zero product property allows us to factor equations and solve them. For instance, x² - 6x + 5 = 0 or (x - 1) (x - 5) = 0. With the zero product property, (x - 1) = 0 or (x - 5) = 0. As a result, the answers are x = 1 and x = 5.
Use the ideal gas law equation to find the molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp.
The value of molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp is 80 g/mol.
What is ideal gas law?The ideal gas law can be given as,
[tex]pV=nRT[/tex]
Here, (p) is pressure, (V) is volume, (n) amount of substance, (R) is ideal gas constant and (T) is the temperature.
For the given problem the modified ideal gas law, (written below) can be used.
[tex]PM=dRT[/tex]
Here, (M) is molar mass and (d) is density.
The molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp. As the density is ratio of molar mass to volume. Thus,
[tex]d=\dfrac{40}{11.2}\\d=3.57\rm\; g/L[/tex]
The standard value of temperature and pressure is,
[tex]T=273\text{ K}\\p=1\rm\; bar[/tex]
The value of ideal gas constant (R) is 0.0821 atmL per mol K. Put these values in the above formula,
[tex]1\times M=3.57\times0.0821\times273\\M=80\rm\; g/mol[/tex]
Thus, the value of molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp is 80 g/mol.

Answer:
As he is driving at spped of 45 mile per hours
This means that if he drivess for an hour he will cover 45 miles but here he only travel for 11 minute
Changing mph into mpm we get 0.75 mile per minute
Multiply 0.75 by 11
We get 8.25 mean he has moved 8.25 mile
As the total distance is 24
So subtract it 24- 8.25= 15.75
He will have to walk 15. 75miles more mean he will have to travel 21 min. More
