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?

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

Explanation:

,

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

frequency or wavelenth of em radiation in a vacuum

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
