Given: a particle M is moving in coordinate plane Oxy. Position of the particle at certain instant t1 is specified by its coordinates xM= -2m; yM= 0m. Velocity projections of the particle are VMx= 1,7m/s; VMy= 0,2m/s. Acceleration projections of the particle are aMx= -3,1m/s2; aMy= -1,1m/s2.
Find: the radius of curvature ρ (in m) of particle's trajectory.
