What is the acceleration experienced by a car that takes 10s to reach 27m/s from rest

Physics
1 answer:
Lerok [7]3 years ago
5 0

|acceleration|  =  (change in speed) / (time for the change)

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

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

That's the magnitude of the car's acceleration.
We don't know anything about its direction.
