Given: a particle M is moving in coordinate plane Oxy. Position of the particle at certain instant t1 is specified by its coordinates xM= 0m; yM= -1m. Velocity projections of the particle are VMx= 3m/s; VMy= -4,6m/s. Acceleration projections of the particle are aMx= 3m/s2; aMy= 4,8m/s2.
Find: the radius of curvature ρ (in m) of particle's trajectory.
