Question

You riding in a car traveling at a speed of 73 mi/hr in a. 60 mi/hr zone, when suddenly you spot a police car parked 20 ft ahead of you. Do you hit the brakes and slow down with an acceleration of -2 ft/sec,for a total time of 3 seconds. Do you get a ticket?

Answer 1

I think yes i do.. cuz using yr information i get the distance i travelled before stopping become 49.62144 m, using the formula distance travelled/time taken= (final velocity+initial velocity)/2.
I am not sure tht its the right answer but using my calculation I got this so hope there! :)

Answer 2

You get a ticket you speed is around 68 mi/hr

Step-by-step explanation:

`V_(f) =V_(i) + a*t`

`V_(i) = 73 (mi)/(hr) *(1 hr)/(3600 s) * (1609,34m)/(1 mi) = 32.6339 (m)/(s)`,
`a=-2 (ft)/(s^(2) ) * (0.3048m)/(1 ft) =-0.6096 (m)/(s^(2) )`

`V_(f) =32.6339(m)/(s)  -0.6096 (m)/(s^(2) ) *3 s`

`V_(f) = 30.8051(m)/(s) *(3600 s)/(hr) * (1 mi)/(1609.34m) = 68.909 (mi)/(hr)`

You still in trouble because the speed is still above the allowed
