Thanks for example, PeroK.
If there were an abrupt transition between hill and flat, wouldn't you expect to lose at least a little speed on your bike due to the impact?
Thanks for the helpful response, haruspex.
How can one differentiate between a smooth and abrupt transition? If θ is 25°, could the instant of transition be treated as (uniform) circular motion?
Hi Lychette,
Thanks for the response.
I'm not sure I follow. The equation to which I was referring was:
vf2=vi2+2aΔx
which is derived just from the assumption that acceleration is constant.
This problem comes from a section before conservation of energy is introduced so it should be...
Homework Statement
A sled goes down a frictionless hill onto flat ground with friction. The sled comes to a stop in some distance. The height of the hill, the angle of the hill w.r.t the horizontal, the initial velocity of the sled, and the coefficient of kinetic friction are all known. I...
