A race car has a speed of 80 m/sec when the driver releases a drag parachute. If the parachute causes a deceleration of -4 m/sec^2, how far will the car travel before it stops?

Answer 1

Use distance equation #d=v_0t+1/2at^2#

Vo is the 80 m/s. Final velocity = 0 since it stopped. Acceleration is -4 m/s^2.

Now, since there are two unknowns in the first equation, you'll have to use a second equation such as #v_f=v_0+at# to find the time. Then, plug t into that first equation to find the distance.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
