No
Acceleration = (change in speed) divided by (time for the change) = (9/3) = 3 m/s2
3 m/s2
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
A truck driver.
v = u + at a = (v - u) / t u = 0 , v = 18 ms-1 , t = 30 s a = 18 / 30 = 0.6 ms-2
yes
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
The white truck sped down the highway.
it does not have enough friction.
