1.1 APPLICATION OF DIFFERENTIAL EQUATIONS FOR PARTICLE MOTION UNDER CONSTANT VALUE FORCES An object of mass m moves from position A along AB = 1 surface (in some problems under angle a) during t seconds (Figures 1.1 - 1.6). Initial velocity is V4. Coefficient of friction is Ilg. At position B the object leaves the surface with velocity V3 and lands at point C with velocity Vc. During the time I the object travels from B to C. P is the engine force moving the motorcycle along AB in problems 11-15. All resistance forces are ignored in problems 11-15. Find the parameters marked with “?" in Table 1.1. Additionally, in problems 2, 10 and 22 find the equation of the trajectory y = f(x) during the motion from point B to C.
