A cyclist is travelling at 15 M per second supplies Breakers so that she does not calls with a wall 18 M away what decelerations must she have?

initial velocity u=15m/s
final velocity v=0 m/s (brake is applied)
distance S=18m
let deceleration =a
using Newton law of motion,
v²-u²=2aS
a=V²-u²/2S
a=0-(15)²/2x18
a=-225/36
a=-6.25m/s²
The cyclist Will have a retardation of 6.25m/s²
