A car travels 263.0 miles in 5.5 hours. How long will it take to travel 363.0 miles at

1 answer:

5 0

From the average velocity calculated, if the car should travel 363.0 miles, the time elapsed will be 7.6 hours.

<h3>How long will it take to travel 363.0 miles at the given average velocity? </h3>

Note that; Velocity is the speed at which an object moves in a particular direction. It is expressed as;

v = distance / time

Given that;

Distance covered by the car d = 263.0 miles
Time elapsed t = 5.5 hours

First we determine the velocity of the car.

v = distance / time

v = 263.0 miles / 5.5 hours

v = 47.8181 miles per hour.

Now, if the car travels 363.0 miles, time elapsed will be;

velocity = distance / time

time = distance / velocity

time = 363.0 miles / 47.8181 miles per hour

time = 7.6 hours

Therefore, from the average velocity calculated, if the car should travel 363.0 miles, the time elapsed will be 7.6 hours.

Answer:

The transverse component of acceleration is 26.32 $m/s^2$ where as radial the component of acceleration is 8.77 $m/s^2$

Explanation:

As per the given data

u=π/4 rad

ω=u'=2 rad/s

α=u''=4 rad/s

$r=e^u$

So the transverse component of acceleration are given as

$a_{\theta}=(ru''+2r'u')\\$

Here

$r=e^u\\r=e^{\pi/4}\\r=2.1932 m$

$r'=e^u.u'\\r'=2.1932 \times 2\\r'=4.3864 m$

$a_{\theta}=(ru''+2r'u')\\a_{\theta}=(2.1932\times 4+2\times 4.3864 \times 2)\\a_{\theta}=26.32 m/s\\$

The transverse component of acceleration is 26.32 $m/s^2$

The radial component is given as

$a_r=r''-r\theta'^2$

Here

$r''=e^u.u'^2+e^u u''\\r''=2.1932 \times (2)^2+2.1932\times 4\\r''=17.5456 m$

$a_r=r''-ru'^2\\a_r=17.5456-2.1932\times (2)^2\\a_r=8.7728 m/s^2$

The radial component of acceleration is 8.77 $m/s^2$
