Question

Some of the fastest dragsters (called "top fuel") do not race for more than 300-400m for safety reasons. Consider such a dragster in this problem, starting a race at rest. After the light turns green, the dragster completes a 400 m race in a time t = 7.5 s.

How many times larger is the dragster’s acceleration during this period than the acceleration due to gravity?

a/g=

If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has travelled a total distance of 1.6 km (~1.0 mile)?
