A large jet plane at the seep of 160km/hr and decelerates at the rate of 10km/hr/s.If the plane travels at a constant seep of160km/hrfor 1.0s after landing before applying the brakes ,what is the total displacement of the plane between touch down on the runway and coming to rest
160km/hr * 1.0s = 160*10^3/3600 = 44.44 m before braking
it then takes 16s to come to a stop
so now use s = vt + 1/2 at^2 to get the distance covered while braking
