Question

A dragster travels 1/4 mile in 6.1 seconds. Assuming the acceleration is constant and the dragster is initially at rest, what is the velocity when it crosses the finish line?plese explain.

Answer 1

The average speed during the 6.1 seconds is 0.25/6.1 = 0.04098 mi/s = 147.5 mi/hr (mph)

That is half the final velocity.

So the final velocity at the fisnih line is 295 mph
