Answer:

Explanation:

kinetic energy will be converted to work of friction

½mv² = Fd

d = mv²/2F = 1000(35²) / (2(8000)) = 76.5625 ≈ 77 m

will be the minimum stopping distance d

What is the acceleration experiance by a car that takes 10s to reach 27m/s from rest
lina2011 [118]

Magnitude of acceleration = (change in speed) / (time for the change).

Change in speed  =  (27 - 0)  =  27 m/s
Time for the change = 10 s

Magnitude of acceleration =  (27 m/s) / (10 s)  =  2.7 m/s²  .
