A car traveling at 80km/hr decelerates at 1.5m/s^2. Calculate
a) the time it takes to stop.
b) The distance travelled in the 3rd second.

physic 
bobpursley,
a. Vf=Viat 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 
physic 
bobpursley,
convert 80km/hr to m/s first.

physic 
Adil,
b)
d=vi+at
d=22.22+1.5+3=26.72
d=22.22+1.5+4=27.72
d=27.7226.72
d=1
is it correct for
