Two Cars: Delayed Start Catch-Up · Krotov #1.12

Physics · mechanics

Problem

Car A starts from rest with acceleration

a_1 = 2.0\;\text{m/s}^2

for

t_1 = 10\;\text{s}

, then moves at constant velocity. Car B starts from the same point

\tau = 5.0\;\text{s}

later with acceleration

a_2 = 4.0\;\text{m/s}^2

. When does B catch A? (Time measured from A's start.)
