(1) What is the particle's speed at t=0 s?

(2) What is the particle's speed at t=5.0 s? Express your answer using two significant figures.

(3) What is the particle's direction of motion, measured as an angle from the X-axis, at t=0 s? Express your answer using two significant figures.

(4) What is the particle's direction of motion, measured as an angle from the X-axis, at t=5.0 s? Express your answer using two significant figures.
