a. Vf=Vi-at solve for t.
b. find distance at t=3, then distance at t=4 and subtract
d=vi+at where t=3, then do it for t=4
b. find distance at t=3, then distance at t=4 and subtract
d=vi+at where t=3, then do it for t=4

convert 80km/hr to m/s first.

b)
d=vi+at
d=22.22+1.5+3=26.72
d=22.22+1.5+4=27.72
d=27.72-26.72
d=1
is it correct for
d=vi+at
d=22.22+1.5+3=26.72
d=22.22+1.5+4=27.72
d=27.72-26.72
d=1
is it correct for
