Verified Answer
Name the opening through which water leaves the body cavity of sponges...
Let 't' second be the reaction time of the driver to be able to put breaks and let 'a' be the acceleration of the car, and full brakes are applied.
(I) distance travelled by the car comma after the driver has seen the signal and before the driver has just apply the brakes.
= velocity * time
= 72 km /hr * t
= 72 * 5/18* t m/sec
= 20 t m/sec
conversion in m/sec
72 km/hr = 20 m/sec
54 km/hr = 15 m/sec
36 km/hr = 10 m/sec
Thus the brakes stopped the car within the distance of (30-20) m
a = 0� - 20�/2(30- 20t )
= -20�/2 * (30 - 20t)
= – (20/3-2t)
similarly,
a = (0- 10�) /2(10-10t)
= -5/1-t
similarly,
a = (0-15�) /2(X - 15 t )
when X : distance travelled by car in third case
20/3-2t = 5/1-t = 15�/2(X - 15t)
t = 1/2 sec
X = 18.75 m.
