Two particles, A and B are travelling around a circle of redius 2m in opposite directions. the velocity of particle A, has a constant magnitude of 5m/s. the velocity of particle B, vb=c t(hut), where t hut is a unit vector that is tangent to thetrajectory. if c=2.5m/s square.
a) find the time at which particle A and B collide
b) compute the accelerationof particle B before the collision. express answer in t hut, n hut, b hut coordinate system
