Kinematics in one dimension

  • Thread starter Struggling
  • Start date
ok ive just cracked the ****s, for this question:

A car rolls gentley(Vo=0 m/s) off a vertical cliff. How long does it take for it to reach 100km/hr.

why cant i use V = Vo + at
where:

V= 100
Vo = 0
a = 9.8(gravity)
t = ?

the only equations ive been given to do this are:

V = Vo + at
V^2 = Vo^2 + 2ax
x=Vot + 1/2at^2

ARGGGGGHHHHHHHHHHHHHHHHHH!

Thats a good question, why can't you use it?
What did you get for an answer using it?
