I am currently doing a project involving an object sliding down a slope and falling freely for a given height afterwards. The horizontal distance is recorded, as is the angle of the slope. I have been trying to create an equation for u (the initial speed) from this data, but I haven't been able to. We are given that:
y = x(tan[theta]) - ((4.9x^2)/(u^2))(1+tan^2[theta])
y = vertical displacement (known)
x = horizontal displacement (recorded)
[theta] = slope angle (recorded)
u = initial speed (required)
This seems to be a slight variation on a few other problems I've seen on this forum, and try as I have, I haven't been able to relate that help to my situation - mainly because I have to use SUVAT.
I can't seem to arrange the equation in a suitable form to easily give 'u'. I'd be really grateful for any help you could give me.
Thanks
