intial velocity is 45km/h, final velocity is 0, time taken is 3 seconds,calculate the retradation of the vehicle and distance tr avelled

Answer:
v= u+at
0=45×1000×60×60+3a
_3a=16200045
a=5400015m per sec
Answer:
Acceleration=12.5/3m/s^2=4.17m/s^2
Explanation:
Initial velocity u = 45 km/h = 12.5 m/s; Final velocity v = 0 m/s; time t = 3 s, acceleration a.
[a=v-u/t] : a=0-12.5/3=-12/3m/s^2
(Retaradation=-(-12.5/3)=12.5/3.

Explanation:
Just read the story :)
20.4 years is 20.4/10.2 = 2 half-life cycles, which means a quarter of the starting mass or 15.2 g will remain after this time.

Using the pressure law (P1 x V1)/ T1 = (P2 x V2)/ T2 where P1= the initial pressure V1= initial volume T1= initial temperature and P2= the final pressure V2= the final volume T2 = the final temperature and temperature is always in kelvin
