.4j A particle is moving with a velocity of U 7.4 The particle's acceleration is 0.18i-0.9j. +3 S At this instant the particle is moving along part of a curved path which can be estimated as a circle of radius R. This curving is provided by the component of acceleration perpendicular to the motion of the particle. What is the magnitude of the component of acceleration perpendicular to velocity? Answer in s2 Answer:
