Answer:

AD= 10

Step-by-step explanation:

First you want to find your <u>Scale Factor</u> which is 9/6 (simplified: 3/2). Then you want to cross muliply with the other fraction being 15/x to get the equation 3x=30. Then you want to divide both sides by 3 to get your answer: AD= 10.

A car is traveling at when the driver sees an accident m ahead and slams on the brakes. What constant deceleration is required t
EleoNora [17]

Answer:

Deceleration = \frac{v^2}{2a} units/sec^2

Step-by-step explanation:

Given that a car is traveling at when the driver sees an accident m ahead and slams on the brakes.

i.e. if he is coming with speed v units/sec say, he has to make his velocity 0.

Distance travelled = m units

Initial velocity = v

Final velocity =0

Use the third formula as

v^2=u^2+2as\\0=v^2+2am\\a =\frac{-v^2}{2a}

So he has to apply an acceleration of \frac{-v^2}{2a} units/sec^2 to stop the car in time to avoid a pile up.

Deceleration = \frac{v^2}{2a} units/sec^2
