Particle Motion revisited

Ex. A particle moves in the [pic]plane so that at any time t, [pic], the position of the particle is given by [pic], [pic]

(a) Find the velocity vector when [pic]

(b) Find the acceleration vector when [pic].

Ex. A particle moves in the [pic]plane so that at any time t, [pic], the position of the particle is given by [pic], [pic]. Find the magnitude of the velocity vector when [pic].

Ex. A particle moves in the [pic]plane so that [pic] and [pic], where [pic]

(a) Find [pic] and [pic]

(b) The path of the particle intersects the x-axis twice. Write an expression that represents the distance traveled by the particle between the two x-intercepts. Do not evaluate.
