You are speeding your 1800 kg truck down Ferguson on a Friday night at 29 m/s. You see a squirrel in the road
and slam on the brakes to avoid hitting it. The brakes plus the road friction generate 5000 N of force on the car,
How far will your car skid before it stops? Do you hit the squirrel if you were 100 m away when you started
braking?
W =
= KE
W = Fd
KE =
mu?

Would like to . could you translate to english

A) acceleration. this seems to be the one that makes sense.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
