v²-u²=2aS
S=distance travelled (=stopping distance)
a=acceleration
= 10 km h-1 s-1
= ? m s-2
u=initial velocity = 120 km h-1
= ? m s-1
v=final velocity = 0 m s-1
Convert all quantities to metres and seconds.
Solve for S.
A car has constant declaration of 10 km/h/s until it stops. If the car's initial velocity is 120 km/h, determine its stopping distance.
