A police cruiser is travelling at 24 m/s and slows down at a rate of 0.65 m/s2 until it stops. The distance traveled by the cop while slowing down is closest to
A.0.44 km.
B.0.38 km.
C.0.42 km.
D.0.36 km.
E.4.0 km.
OK use vf = vo + at to find 't' (note 'a' is negative)
Use this value of 't' x = xo + vo t + 1/2 a t^2 to find the distance in METERS..... (xo=0 in this instance)
ok Im stuck since I plugged the numbers in and got 24 m/s/.65m/s^2 then (24+0)?2 then I got 443.076999977 what do I do?
You have the correct answer in METERS..... Convert to Kilometers and the answer is 'A'
