An airplane accelerates down a runway at 3.20 m/s/s for 8 s until it finally lifts off the ground. Determine the velocity at take-off.
___________ distance is the total distance the vehicle
travels when you add the driver’s reaction time (thinking distance) and
the distance a vehicle travels under the braking force (braking distance)
thinking
stopping
breaking
______________ is the distance your car will travel once you hit the brakes before it comes to a complete stop.
thinking distance
stopping distance
breaking distance
What is the relationship that you can see between speed and total stopping distance?
The faster you are travelling, the shorter the total stopping distance
The slower you are travelling, the longer the total stopping distance
Thinking distance increases a lot, and so does speed
The faster you are going, the longer the total stopping distance
