Answer 2

HELLO MATE

According to first law of motion

kinematic equation

v=u+at

given u=36km/h=10m/s, v=0,t=10s

0=10+10a a=-1m/s²

here acceleration is negative it is retardation

by 3rd kinematic equation

v²-u²=2as

0-(10)²=2*-1*s

0-100=-2s

s=100/2

s=50

therefore s=50m

distance traveled is 50m

distance traveled is 50mand negative acceleration is -1m/s²
