Question

a train is traveling at a speed of 60km/hr. Brakes are applied so as to produce a uniform acceleration of -0.5m/s². Find the distance before it is brought to rest.

Answer 1

${v}^{2} - {u}^{2} = 2as \\ {0}^{2} {16.6}^{2} = 2 \times - 0.5 \times s \\ - 275.56 = - 1 \times s \\ 275.56 = s$
