Question

a scooterist in motion at 36km/h sights an obstacle 35m away from him when brakes are applied, retardation of -2m/s^2 is produced. would he be able to avoid the accident?

Answer 1

in this situation

u = 36 km per hour = 10 m per second

v = 0 as driver apply brakes

t = 5 seconds

a = v - u divided by t

so a = -2 m per second (-due to retardation)

s =ut + half a(t)^2

s = 50 + (-25)

s = 25 metres

So he couls avoid the accident

Answer 2

Answer:

Yes he can avoid an accident.
