A car travelling at 20 m/s brakes with a constant deceleration of 5.0 m/s². Calculate the distance it travels before stopping.

Dynamics Challenge #7 — Braking & Kinematics

Braking distance
at 20 m/s.

Dynamics Easy

A car travelling at 20 m/s brakes hard, decelerating at a constant 5.0 m/s². Calculate the distance it travels before coming to rest.

Constant deceleration — the timeless suvat equation does it in one step.

Hint: no time given, none needed: \( v^2 = u^2 - 2as \) with \( v = 0 \). Solve for \( s \).
