Answer:

1) data:

vi=1.66 m/s

vf=6km/hr into m/s

6 x 1000/3600

vf=1.66 m/s

t=15.5 hr into sec

15.5 x 60

t= 930 sec

required:

S=?

a=?

solution:

we know that; according to the acceleration:

a=(vf-vi)/t

a= (1.66-1.66)/930

a=0/930

a=0ms-2

we know that; according to the 2nd equation of motion:

S=vit+1/2at2

S=(1.66)(930)+1/2(0)(930)2

S=1543.8+1/2(864900)

S=1543.8+864900/2

S=1543.8+432450

S= 433993.8 m
