Abrand new corvette can go from 0 to 85 miles per hour in 4.8 seconds.
calculate:
a. its acceleration.
b. its average velocity.
c. the distance it travels during the 4.8 as it accelerates.

(A) 7.9 m/s^{2}  

(B) 19 m/s

(C) 91 m

Explanation:

initial velocity (U) = 0 mph = 0 m/s

final velocity (V) = 85 mph = 85 x 0.447 = 38 m/s

initial time (ti) = 0 s

final time (t) = 4.8 s

(A) acceleration =

         = = 7.9 m/s^{2}  

(B) average velocity =

     = = 19 m/s

(C) distance travelled (S) = ut +

  =  (0 x 4.8) + = 91 m

what was the answer?
