u=28 a=-9.81 v=? s=22
a is negative because the car is going up, its going against the gravity and we know gravity always acts downward
v^2=u^2+2as
v^2=28^2+(2x-9.81x22)
v=18.8
Then round off, therefore v=19

Easy, it indeed took 90mins for the 1st half life
Anybody know? Answer is B, why isnt half life 90 minutes?

Saad Mughal can help you in this. cz i m not very good at physics. srry.XPC?? danial 234
Has anyone else noticed that in all pV=nRT, when converting from cm^3 to dm^3 , they multiply it to 10^-6 and not 10^-3. Can someone please explain that? ASAP! Thanks!
It's not from cm^3 to dm^3. It is from cm^-3 to m^3, cause u are converting to SI unit, that's why is m^3.
