CONSTANT-SPEED RAMPS 1. Introduction It is experimentally
... Definition 3. A ramp with external force is a triple (γ, n, F) where F : [a1 , a2 ] → R2 is a smooth function and (γ, n) is a ramp. Given a positive number m, a solution of the ramp with external force (γ, n, F) is given by a curve β(t) = γ(h(t)) (Notice that β is just a re-pametrization of the curv ...
