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

Find the diameter of Oo. A line that appears to be tangent is tangent. If your answer is not a whole

Trava [24]

Answer:

Diameter = 9

Step-by-step explanation:

Let the diameter be represented as x.

Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:

(16 + x)(16) = 20²

256 + 16x = 400

Subtract 256 from each side

16x = 400 - 256

16x = 144

Divide both sides by 16

x = 144/16

x = 9

Diameter = 9
