For a short time a rocket travels up and to the left at a constant speed of v = 650 m/s along the parabolic path y=600−35x2m, where x isin m. The origin of polar coordinate system is the same as the origin of the rectangular coordinate system xy.

Part A

Determine the radial component of velocity of the rocket at the instant when its transverse coordinate θ = 60∘, where θ is measured counterclockwise from the x axis.

Express your answer to three significant figures and include the appropriate units.

Part B

Determine the transverse component of velocity of the rocket at the instant when its transverse coordinate θ = 60∘, where θ is measured counterclockwise from the x axis.

Express your answer to three significant figures and include the appropriate units.
