Answer:

I think they need the slope of the ram(degree) .

& current gravitational acceleration

& the length of the ram and also l don't think mass of the cars are not needed becoz the acceleration of the cars are given by its,

Gravitational acceleration * sin( slope).

So then use that in v^2=u^2+2as equation.

s for length

a for acceleration

v for end velocity

u for start velocity
