Question

In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straightaway at 71.0 m/s. The driver of the Thunderbird realizes that she must make a pit stop, and she smoothly slows to a stop over a distance of 250 m. She spends 5.00 s in the pit and then accelerates out, reaching her previous speed of 71.0 m/s after a distance of 280 m. At this point how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?

Step 1

Let* AB* is first interval and after the pit *BC* is second interval.

Step 2

Let acceleration in first interval is *a*. So,

Step 3

Negative sign show the deceleration. Now, let accelerat...
