initial velocity of car = 90 km/h
changing km / h into m / s.
90 x 5 / 18= 25 m / s
final velocity after coming to rest will be 0
acceleration = -2 m/s²
acceleration = final - initial /time taken
- 2 = 0 -25 / time taken
- 2 = - 25 / time taken
-2 × time taken = - 25
time taken = - 25 / -2
time taken = 12.5 seconds.
time taken by the car to stop is 12.5 seconds.
