Question

John is approaching a stoplight moving with an initial velocity of 30.0 m/s. The light turns yellow, and
John applies the brakes and skids to a stop. If John’s decelerates in a rate of 8.00 m/s^2, then
determine the displacement of the car during the process.

Answer 1

v^2-u^2=2as here u=initial velocity,v=final velocity=0m/s,aceelaration=-8m/s^2 distance=s
0*0-30*30=2*-8s
distance=900/16=56.25 meters
