Constant Acceleration Formula: Find a Dragster’s Final Velocity Without Time

Converting 0.250 mi to about 402 m and applying the no-time constant-acceleration equation gives a final dragster velocity of about 145 m/s.

Question

A dragster’s finish-line time is unknown. It accelerates from rest at 26 m/s² over a quarter mile (0.250 mi). Find its final velocity.

Evidence boundary

The original prompt gives a quarter mile (0.250 mi), not 402 m. The Answer follows the textbook Solution by converting 0.250 mi to about 402 m and applying the constant-acceleration kinematic relation used in that worked example. It does not separately model changing acceleration, reaction time, traction limits, or aerodynamic drag.
