Example Question #791 : Calculus
A race car is traveling at a constant 50 m/s when the driver suddenly hits the brakes. Assuming a constant deceleration of 10 m/s2, how far will the car travel before it comes to a complete stop?
Not enough information is given.
To find the change in position of the car, let us start with the car's acceleration as a function of time:
Since acceleration doesn't change with time, it has a constant value.
(the negative is used to represent deceleration).
We can then integrate this function with respect to time to find velocity.
Where v0 represents the initial velocity, which was given to us as 50 m/s.
We want to know the time where the car comes to rest, meaning where v(tr) = 0.
Solving
for tr gives our time at rest, 5 s.
Now, we can integrate our velocity function with respect to time to find our position function.
Since we're not interested in the absolute position at the time of rest, but rather the change in position, we can move the x0 term to the other side of the equation:
Plugging in our values for
and
We can find how far the car travelled after the brakes were hit, our
quantity, to be .
