Answer: -1.5m/s^2

Explanation:

Initial velocity V1 = 14.0 m/s

Final velocity V2 = 5.0 m/s

Time taken = 6.0s

The car's acceleration = ?

Since acceleration is the rate of change of velocity per unit time

i.e acceleration = (V2 - V1) / T

Acc = (5.0 m/s - 14.0 m/s) / 6.0 s

Acc = (-9.0m/s) / 6.0s

Acc = -1.5m/s^2 ( the negative acceleration means the car is slowing down)

Thus, the cars acceleration is -1.5m/s^2

How do lines of latitude affect how direct or indirect the Sun’s rays are on the Earth?
Sonja [21]

Answer:

Explanation:  We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun. As we orbit our Sun, our axis always points to the same fixed location in space. Our northern axis points almost directly toward Polaris, the North Star.

At the nose of a missile in flight, the pressure and temperature are 5.6 atm and 850°R, respectively. Calculate the density and
Contact [7]

To solve this problem we will apply the definition of the ideal gas equation, where we will clear the density variable. In turn, the specific volume is the inverse of the density, so once the first term has been completed, we will simply proceed to divide it by 1. According to the definition of 1 atmosphere, this is equivalent in the English system to

1atm = 2116lb/ft^2

The ideal gas equation said us that,

PV = nRT

Here,

P = pressure

V = Volume

R = Gas ideal constant

T = Temperature

n = Amount of substance (at this case the mass)

Then

\frac{n}{V} = \frac{P}{RT}

The amount of substance per volume is the density, then

\rho = \frac{P}{RT}

Replacing with our values,

\rho = \frac{5.6*2116}{1716*850}

\rho = 0.00812slug/ft^3

Finally the specific volume would be

v = \frac{1}{\rho}

v = 123ft^3/slug
