Determine the energy lost, due to friction, as an 8000 N car that skids to a stop, if its initial velocity was 12 m/s.
chubhunter [2.5K]

Answer:

<em>58,800Joules</em>

Explanation:

The energy lost is equal to the workdone by the car as it skids.

Workdone = Force * Distance

Given

Force = 8000N

Get the distance using the equation of motion

v² = u² - 2gS

0² = 12² - 2(9.8)S

-12² =  - 2(9.8)S

-144 = -19.6S

S = 144/19.6

S = 7.35m

Calculate the required energy

Workdone = 8000 * 7.35

Workdone = 58,800Joules

<em>Hence the energy lost due to friction is 58,800Joules</em>

aleksklad [387]

Answer:

The answer is 5 seconds;

Explanation:

<h3>a) We know that the speed(V) is 15 m/s and acc. (a) is 3 m/s^2 </h3><h3>b) The formula for the acceleration is  a=\frac{V}{t};</h3><h3>Using this formula we can define the next equation:</h3><h3>3 =  \frac{15}{t} , where  t is the sought time. After solving the equation we get that t is 5; </h3><h3> </h3><h3></h3><h3></h3>
