Question

a dragster starts from rest and travels 1/4 mi in 4.7 s with constant acceleration. what is its velocity in mi/h when it crosses the finish line?

Answer 1

The dragster's velocity in mi/h when it crosses the finish line is 159.2 mi/h. This can be calculated by taking the distance traveled divided by the time taken, multiplied by 3600 (for conversion of seconds to hours).
